Hello. Well, it sounds very interesting. Your work shouldn't be a problem, for the team has said there won't be another patch to fix bugs. So you're just helping us, who use the english version. Of course it needs somebody of the team to confirm that there is no problem.
Concerning the translations, i'm sorry i can't help you, i don't have enough knowledge in german. Don't worry, even a very bad translation would be better than a total lack of understanding! (At least for me

)
Another point, if you agree i would like you to send me your english text file once you will have finish, because i'm translating the mod in french, and when i encounter german sentences... well i'm a little embarrassed
