on skywars and one in the chamber (and possibly other minigames, i havent checked), i am receiving an issue where some of the other players are invisible, but visually, it appears they are standing where they first spawned, not able to be hurt or interacted with. they are able to play normally and attack other players, and there is no way to see where the invisible players are (cannot see items in hand or armor), unless if they place blocks or drop items. this bug doesnt happen to all players, only 1 or 2 are invisible in any given game, sometimes none at all. i dont think this is the result of cheating, because i have been invisible myself to other people (as in, i could tell other players could not see me while fighting, or trying to kill the ghost player where i spawned). this has started happening since the 1.20 update, and i have not experienced it on other servers.
