Hello!
I think I found problem with MCMT and Mohist. The chest GUI is immediately closed after right click, also it's the same with pneumaticcraft machines. I'm not on my computer rn so I can't share more logs.

The same problem you find with the blocks:
Dropper, Dispender, Blast Furnace, Ender chests, Trape chests, Lectern, Smoker, Brewing Stand and Cinder Furnace(The Twilight Forest).

Interesting I guess I need to figure out how to poke mohist with a debugger

Also the Issue is the same even if you blacklist them from te BUT I am not 100% sure if the blacklist even worked because of the broken commands from mohist side.

Yeah MCMT and some other mods commands are broken on Mohist

I did some more testing and found out that hoppers are effected too but what is even more interesting is that Dropper and Dispender stoped working, they dont shout anything even with items in them. Also hoppers stoped to pick up things and trapped chest are still able to give out redstone signals.

LIttle Update this Issue has been fixed in a pre version of MCMT that you can find on the discord.
