i tried mod for 1.16.2 on 1.16.4, it works, but ports are messed, depend on facing of module and aren't consistent.
.4 and .3 patches don't seem to change anything relevant, but i dont know if mod behaves properly on .2

Hey, sorry about that, this slid in with a pull request a few versions ago and nobody noticed. Fixed as of 4500d14, update on Curse is on the way.
