When players use a Spectre Key to go to the Spectre dim it causes them to get timed out from the server. Logging on causes them to time out with no errors on either end. Any efforts to move (teleport) the player ingame fail. The location and dimension data must be manually removed from their player's data file to get them out of the Spectre dim and back to the server spawn.
