Well I'm working on total conversion mod so even when I started not long ago the list is not so short.

[I will write if when game is sometimes loaded succesfully the thing's working ok]

->new animations (working) and skeletones (working)
->new terrain textures (working)
->new menu and loading screens and quotes (working)
->lots of new units (working) with lots of new models and textures (all of them are working)
->new vegetation (working)
->new sky (working)
->new music and lots of sounds (working)
->new formations AI (working)
->new grass (working)
->new custom battlefields (working)

So.. lol...All of these are working when the battle loads succesfully althought still very often during loading a custom battle I get this error! and then crash ;(

I'm so tired of searching for the bug, so I decided to look for more professional help :/

If a thing works once, it could crash later without real reason?? That's totally strange to me.
