Talk about an interesting situation
On the one hand we have the problem Myrthos points out: the threads risk getting very cluttered.
On the other we have the problem Forktong points out: the non-german versions are not supported, and for very good reasons! we're still working on them and there are known problems with mixing non-german text with german text, potentially ruining the entire game.
The best thing we can think of is to open up a help/tips/tricks thread in English/French and move them from here to there. This will allow members of the german audience to post questions directly to us. There are issues with the language hacked versions, and we'll probably see those pop up too, but we won't give any support for those, so hack at your own risk
