Thrawns revenge mod crashing on byss

[Bad_Karma]

Playing the galactic conquest, and am trying to take byss, have space superiority, the game at this point is already won the AI just doesn't know it yet, however they have discovered a superweapon on byss... a game ending crash, I can conquer the world, however, it instantly spawns an empire admin building, and I can't extract my units, they're invisible, and I can't land anything (that triggers the crash) and I can't sell the admin building like I can when this happens on other worlds.

This is very repeatable, and the last time I tried I took the planet with only 5 units, so there were empty slots on the planet, so invading a second time would not be like trying to put 11 units down on a planet that already had 10.

Any solutions to this?
