Hey, I just created a modpack with this mod and on singleplayer it works great with no problems, but on a server I created, for some reason it goes through the chopping cycle, but then the tree doesn't get chopped down, it still gives the player the right amount of wood, it's just the tree is still stuck there, and it seems like there may be some invisible blocks there as well. I ended up removing the mod from the server for now, but I can reupload it and provide a log if needed.

Nevermind, I was able to figure out the problem, I just had to add the Connectivity mod to my modpack which fixed the ghostblocks.
