Good news, the new "Graphics paging" option saves about 30% of RAM memory usage (with bigger maps, more RAM saving), and it should remove virtually all MAF errors.It replaces the Viewports system. This system can be activated in BUG Options screen. It should be auto-activated by default. See Version 33 Changelog under the Features Tab above for more details.

An I/O error in what context? If it's the operating system reporting it to you, that can be a sign of impending hard disk failure.

lol at Timber Wolf on one of the pictures. I hope you got permission to use that from the owners of Battletech lol.

But in all seriousness, Timber Wolf is probably my all time favorite mech. I've been blasting through the MechWarrior games with that thing since I was a little kid. Of course, that horrible pay2win Mechwarrior Online pretty much raped my childhood, but I still get a warm feeling in my heart when I think about shooting the pixelated eyesores that made up the MechWarrior 2 mech roster.

But i digress. The prehistoric era has always been an agonizingly tedious grind for me. Has that changed recently?

this is the best mod for the game and how civilization should be. my only complaint is that it takes longer to build something that it does to research technologies. its annoying that every tech for the most part seems to unlock new buildings and i get like 10 new buildings to build by the time i finish one.

Its easy my friend:) Click on a city and hold shift and leftclick on the buldings in the menu. If your city produce enough hammers you can build 3-4 or more buldings in 1 round;)

Just want to say a massive thank you to all involved in this mod. It is incredible. Being a CIV4 fanatic (CIV5 is OK, but not as good as 4), this mod just takes CIV4 to a completely new level. There is so much awesome in this mod, I don't even know where to start. So yeah, I will just again give my heartfelt thanks for developing this mod to all involved and also for the fact that you are still supporting and improving it. /salute
