Putting up a table over something causes the player to float very high above the map along with traps them in place of where the seat it. Relogging supposedly cures it. Tested it on 20+ people now. Entertaining if anything.
Experienced this bug as well. You can jump higher until you see a black screen, and if you stay still for a minute or so, you’ll land back down at the ground. Relogging works as well.
