I don't see a crashlog. Can you see if you can fix that?

Sorry about that - was trying to reduce noise.

I just recreated it with 0.9.1g on a test world with reduced mods. Hopefully I do this right and this gives you more information.

Crash Log

There is still a lot of mods. Dynamic trees does a bunch of stuff that might break in large modpacks. I recommend binary-search testing to see which mod is causing the issue.

I'll recreate in isolation in a bit, but 18 is not a large mod pack (a few of those are a single jar with various registered components)... and the majority of those were incidentally added when I recreated the issue. They were absent when I originally performed the isolation test.

Also, for clarity, if it helps - the error only occurs when planting a cone after chopping down a spruce... I can't recreate it under any other event.

Thanks for reviewing. I don't want to understate how amazing this mod is.
