Issue: Lumberjack{1.2.0.33} crashes dedicated Forge 1.10.2 build 2007 on startup

crash report:
https://gist.github.com/f01516948e64a6807a472784f1c345a5

fml server latest:

Could you test with https://jenkins.dries007.net/job/Lumberjack/34/ quick?

If could post the FML latest again if you get it started, it should tell me what mod is causing the issue and I can take measures to prevent it from happening/contact the author(s). Technically they are (99% sure) responsible for this issue, but I seem to be the only one using ToolMaterials in this way, so no one seems to notice 😄

I'm working on a better fix, but builds since 34 will not crash; some axes will be missing though.
