Orbital wars bug report:
https://forum.faforever.com/topic/358/orbital-wars-1-37-for-all-game-versions
I also checked both mods with the new gameversion and did not find a single error.
(I test all mods with the develop version of the game before the patch is out, but maybe i missed something so please report)
