I finally got my buddies 250 hw 1 map pack into HWU so you will be able to play all the classics that he had converted using his map code. At the moment i am editing his maps due to a problem i found. That problem is that all players get an unseen pride of hiigara, its no where on the map but its listed in the production queue. This means that if you play on these maps atm you cant win, that is until i disable that POH which im doing right now. BAH i hate having to edit 250 maps X_X.
EDITED
Turns out its not just the MS but the carrier that shows up in the queue if its in starting fleet for the map in question as well as other ships listed which then count towards the unit cap, which means i have to disable everything.
Edited again
Turns out i could finish it faster by deleting the starting ships all together, which i did and got finished a few mins ago so all 250 hw 1 maps are done for HWU.
Good luck with editing 250 maps, I wish no one would have to do that manually, I guess there isn't a way to make changes that would apply to all maps.
He already did it..
Oops. I've not encountered that issue myself. Maybe because I despawn the ships using a gametype script after loading the level.
