How often it happens: Any time any player exits the Wall of Flesh Arena via the warp plate.
The Wall of Flesh arena’s exit warp plate teleports players to the Old One’s Army arena entrance warp plate. Previously this was a minor inconvenience at worst, but now that the OOA arena entrance warp plate is blocked off, players who exit the Wall of Flesh arena via its warp plate are teleported into the blocks obstructing what was previously the OOA arena entrance plate. Anyone can just use a recall item,
/spawn, or warp somewhere else using commands to escape, but not everyone knows that.
