That's strange then, the pack I released only had one of my factions in it which I can get working fine on its own, it's just when I load both factions.
I'll have to look right into things to see if I can track down where this bug is coming from...
My second faction has so units with the same name just remodels or retextures stuff like Huts, Houses, etc which all factions will have, maybe there's some problem there, but that wouldn't explain why you got that bug with only one of my factions, unless I had some duplicate stuff, but then again how come it worked for me...?
Edit: I loaded up the game and started a new game with faction 1 Necribus, it ran fine. I quit the game back to the menu and started another new game with faction 2 Hyperion, it ran fine (not much to do with this faction at the minute though as there's only a few things in it but it loads up in game fine).
So both factions worked fine. I quit the second game returning to the menu again, now starting up a third game a set some of the opponents as faction 1 Necribus while I and another opponent was faction 2 Hyperion and the game loaded looking ok but at the last step of Initializing it just closed down, no error message at all this time. The crash log isn't updated.
I'm gonna mess about with stuff now to see if I can find anything.
Edit: Ok so I changed the name of every unit so there are no units in both factions with identical names, the game still closed immediately. Next I did the same to the upgrades, nothing changed. Now strangely when I renamed all the particle images (which were the same between factions) I now get the 2D mip map error.
Before I look into it more will having GUI buttons with the same names between factions effect anything or am I looking in the wrong places?
