Describe the bug
Sign lifts do not work unless you have build perms in the said region, so public mines are a no go, upstairs in taverns aswell.
/Stack does not work at all.
/vote pretty sure you know about this does not work and when you vote on the forums you do not get any rewards.
/sit you- sit into blocks which yea.

How did this occur
The- update in general 1.20.6 has broken a lot, you can recreate any of these by testing them yourselves, since you guys are permitted in all regions I would get on a alt to test the sign lifts.

Expected behavior
Baiscally expected all of it work and it doesnt.

Minecraft version:
1.20.6
