I tried to use this mod with other mods I have and I at first noticed a slight hesitation about once a minute or so, figured maybe it was due to loading new Chunks at first.

Then today I went to load an old world, did that successefully so closed that world and opened another to have a crash.
I read through my logs to find that BonSai Tree 3 did indeed crash the system. I'm hoping to help resolve the problem as I love your mod.

I'm including my crash report and my long list of mods I and my family use on our home server

You are missing libnonymous.

This looks like a version issue with the dependent Libnonymous. Class not found likely means you are using a older version of this mod that does not have the class that Bonsai uses.

Try updating the version of Libnonymous (backup first though as that might break your other mods that use that library mod.
