When I went over some bows in the creative gui the game just crashed.
From the crashlog it looks like a problem with the tooltip but I don't know if its from MCDW alone or from the combination with another mod.

I just went over an old crash issue and it looks to be the same issue there with just another mod causing the problem. Maybe it is the LevelZ mod in this case because it adds tooltips to all weapons and tools

Yes I was right LevelZ is causing the issue, I'm gonna contact the LevelZ Developer ^^
