I have got one BIG Problem with the custom techtrees:
Since TA release I made a techtree for my custom race, and everything worked fine. But since today, the techtree won't work anymore. When I try to start a game with this techtree, the game crashes

I havn't done anything special with it today, just added some new techs. I have already deleted these new techs, but it still doesn't work.
I don't really know what to do now, because I don't want to play this game without this techtree, but I also don't want to re-do the techtree, because it would take weeks.
It would be really nice if someone could try this techtree and tell me whether it works or not. And it would be even better if someone could just tell me whats wrong with this techtree

And here it is:
(btw. it is german, but that should be no problem)
Edit: I deleted the code, because it was too long and I have already solved the problem, so the code is not necessary anymore.
