I've been running Entropia Universse via PlayOnLinux (Manjaro - Arch Linux based) occasionally. All is running good except for a few minor bugs, not sure what is missing to satisfy them.
1) Waypoints (/pos) is not displaying the current avatar's coordinates in the chat and clicking coordinates entered by other players will not add a way point to the map
2) Switching to/from Fullscreen (alt+enter) is buggy, is there a way to disable the whole alt+enter fullscreen-function?
Great news! h0ek did a great job on getting the Waypoints working.
Use his script to install the game:
