this mod is working very well. it has solved two different gun mods' reload key conflicts. but it is not compatible with the inventory move mod (https://www.curseforge.com/minecraft/mc-mods/invmove-forge/files/all?page=1&pageSize=20)

And 1.12.2

Issue is confirmed when testing with InvMove-1.12.2-0.4.6. Fixed in v1.3.3.1.
