Many thanks for fixing the bug in versus mode. It will no longer get stuck at the conclusion of a game. Instead the "game over"-message is now displayed correctly and it is possible to continue with the main menu.
However we have encountered a minor bug when selecting ships: While displayed correctly for player 1 shield and speed is always displayed as maximum (5) for players 2, 3 and 4.
Not a bug but a feature request:
Team battle with 2 players does not allow them to join the same team - which is something I would sometimes like to do when playing the game with a friend. For this mode friendly fire should be without effect, so one can concentrate on the mission and the environment.
