I'm trying to attack Sobuvu in the tutorial. I've sent three assault transports loaded with my attack fleet, and they're sitting under cloak well away from any wormhole. Now those transports can't be unloaded. I've tried moving them around and clicking unload and it won't work. Any way to fix that? I'd include my save file, but I'm not sure where to find it in Linux (OpenSuse 64-bit).
