I noticed I was diddn't have an embasy with a particualar faction, so I sent an envoy cruiser to take care of it. About twenty minutes later, I opened the diplomacy screen and much to my chagrin I had no embasy there. The envoy cruiser naver made it, but it was still alive. It had gotten itself stuck next to an orkulus starbase... It would travel out a few feet, charge up the phase jump (the "portal" appearing behind the cruiser) and stop next to the same starbase. It continued to travel in this circle untill I gave it some new orders. Dunno if it's been fixed with this recent update, but I thought I'd point it out.
