I read on the mod page that multi-mine may be the cause of this issue but should have been resolved. I attempted to use the fix given on that issue and it kinda worked? If I hold down left click while trying to break the block, it breaks like vanilla. If I almost fully break it but stop, then finish the break, then it will treechop break twice. If I continue to hold it from there, it will treechop break the rest of the way. Using minecraft version 1.20.1 and mod version 0.19.0

Weird, I tested this the other day and it worked well enough. The double-chopping thing has always been an issue that's tricky to solve, as it should really be fixed on MultiMine's end (they trigger block breaking twice sometimes, when doing what you showed). You can always add tree blocks to multimine's blacklist in their config file, which should fix both issues

I'll look into it more soon, thanks for reporting
