from the b8 version of the naruto mod I have the problem that when I scroll down in the creative inventory my game crashes

Could I have any more of the log? It would tell me what rendering code or line is crashing. Also which tab are you in?

Ok I found the issue. This was because the mapping changed due to the fact I forgot to add mappings beforehand so a lot were missing. I've also added override tags so that this cant compile if an issue like this happens again.

#blame @UpcraftLP ;)
