I play on Forge 47.2.0, I have tested Treechop + multimine / Treechop + PFT / Multimine + PFT / each mode individually
I have tinker in the settings with multiple option / tool / tree / gamemode

When I use the 3 mods together it revert to vanilla behavior + multimine
Treechop feature can trigger if I spam left click until breakage there is a slight chance that the log lose a layer
But impossible to trigger PFT entity or Treechop harvesting the whole tree

If I communicate the issue to you it's because multimine work with both mod and there is already a compatibility option in treechop config mentioning multimine, while PFT do work with multimine just fine and a update do fix compatibility issue with treechop I didn't see something about both mentioning somewhere

For the moment my solution is to dish out Treechop but I can't chop fungis anymore and I dont have the visual feedback of treechop anymore

Anyway I love your mod and can't imagine playing without it since I have test it

Thanks for this report, im planning on making full compatibility with Multi Mine in the future.

+1 on this to watch, hoping a fix comes out soon!

A temp fix I found out was adding all logs to the blacklist in multimine config!!
