Got a LOST ALPHA Game problem?
Don't post it here or anywhere else on Facebook. Why? The ModDB and FB formats make posts descend to the bottom with each new one and your concerns can easily be lost. Too many pages and posts can make your problems disappear.
Where to go?
The GSC Forums LOST ALPHA section is designed to post Game problems and to provide answers. In addition the format makes it easy to find previous problems posted where you may not have to ask.

With the announcement/new vid of STALKER 2 I see more traffic here, so I wanted to give a quick guideline on the different LA DC versions.
LA DC 1.4007: Is a mix of all the original teams work along with the RU team. The main thing it did was get rid of a bunch of cut scenes and the “Illuminati” bits along with lots of fixes and adding in more side quests. Must use the Storyline changes v1.08 mod from the launcher for full effect of the story changes.
LB's LADC 1.4007 Compilation: You must have LADC installed. My comp is just an extension of 1.4007, read all the notes. It retains the vanilla ideals, but updates/fixes some more stuff. It adds in the item usage mod for immersion that was released on the RU VK page as well. Also includes an unpacked Storyline changes v1.08 with additional changes by me, so no need to use the mod. This comp will only work with a few mods mentioned in the description. Also contains a newer configurator and bins. Link below:
LA DCE: Was solely made by the RU team, none of the original team (which includes me) had any involvement in it. It does have lots of cool fixes/updates, but it is more like "misery" type game play. The save system has also been changed to a check point save system. Read more about it from my article below:
*All DCE discussion is to take place under the DCE articles comments section.
**LA DC/most mods made for DC and my compilation ARE NOT COMPATIBLE WITH DCE
There is a new version of LA out (DC Extended). Check out the details below for more information.
This news post is to be used more as a resource for LA updates from the RU team/modders.
We wish you a Merry Christmas with the release of Lost Alpha Developer's Cut 1.4007!
We wish you a Merry Christmas with a special full release of Lost Alpha Developer's Cut 1.4005!
THIS IS A ONE STOP SHOP FOR PEOPLE THAT DON’T WANT TO SEARCH AROUND FOR A NUMBER OF LADC 1.4007 UPDATES/MODS AND WHO WANT TO PLAY MORE OF A NEAR COMPLETE...

i just installed the game and when i try to launch this error occurred
Expression : fatal error
Function : mem_usage_impl
File : memory_usage.cpp
Line : 169
Description : <no expression>
Arguments : bad node in heap
i don't know what to do.
Great Mod! But it freezes at the great metal factory near the phone booth on the way to yantar. I've tried to disable all Mods but it didn't work for me. Does someone know how to fix it?
The error massage in the logfile looks like this:

This is a bug from an early version , so i'm wondering what version and mods you have installed ?
I've downloaded the six parts of version 1.4007 and i have no further mods installed except the ones, that are already part of the version.
Approximate stash markers v1.00, autumn vegetation v1.00, paramilitary coloring v1.01, closed optical sights v1.00, darker nights v1.01, extended weather v0.18, extra hardcore survival v1.00, free-range alife v1.03, hidden anomalies v1.01, main menu music from SoC v1.00, old low-poly sidorovich v1.00, PRM weapon pack v2.09, russian voice acting v1.00, static lightning shaders v1.00, unrealistic hardcore economy v1.05
You're problem is , as surprising as may be , the mods Darker Nights and Extended Waether ...these have never worked well together .
Choose one OR the other and it should solve that issue .
As morbid said, but also I believe one of those mods causes that issue as well. You will need to remove them all one by one to see which it is.
The Mod is nice but have some ugly CTD ;) was able to go around that after some testing and trying other ways but its always annoying.Then why Ammo slot is the same as Artefact slot?Its a pain in the *** to refill the Ammo slot if you are in the middle of a heavy fight or surround by 20-30 Animals that pack attack you.You can chose to use artefact or ammo.With every artefact you have lesser ammo ready what is stupid.Then the animation for healing or you reload why you need to shoot or you heal for 15-20 Seconds.Its to much you die many times for all that long animations.Performance is even a little bit Mäh try all option but nothing real help.Have 60FPS constant but many times a lot of Micro jumps and i don't find a way to get rid of them or all max mega ultra or all garbage low its the same nothing change apart of the visual but the Micro stuttering remain.
Ammo and artefacts are attached to the belt ..now i don't know how big your belts in RL are , but mine are pretty small . This means not a lot can be attached to it so i have to play it smart .
The animations can be annoying , i agree , but hey it can not be all perfect . In real life it would take time to reload or bandage yourself .
The micro-stuttering is something that happens , period .
If you would read up on it , you would know that the engine was created in a time that multicore CPUs didn't exist .
And eventhough a lot of fixes have appeared over time , you will experience micro-stuttering regardless .
People think that having a powerful rig will make this game run perfectly , it just won't ..no matter how much you will fiddle with the settings , the best settings are always depending on your rig and the realization that it is a game that is 17 years old ( the engine that is ) .
Try to find the bottleneck in your rig and see if you can do something about that , the game is what it is .
In real life no one will attack a huge artefact Container on his Belt as Soldier but that's the Game :) Same for ammo as soldier i prepair my Mags before a Firefight and put it in my Bodyarmor Pockets that was make for that on the Belt only Cowboys had there ammo :). To the animation how much time a Soldier in the real life get Pack attack from 20 Wild Animals that eat each 10-15 Bullets?Its even the game but real 15 Seconds to Heal where you put away in front of your enemy your Gun then after 15 Second to reload is real to much.But anyway i stop to play for now this Mod as i have a constant CTD in Death city after the cutscene where i get to know that im Strelok.I can recover my stuff and fight a little bit my way out but after 1 Minute the game CTD.I Take a look in the Console to see what cause it and i find 4 Errors in the Mod 1 is in Death City 2 refer to the Old road and 1 to something with Military.
