Bug

[Niknud]

If you have a breach drone on your ship and you leave the sector with it as long as you do not kill it any enemies that teleport to your ship will be stuck in the rooms they teleported to.

This isn't a bug, if there's an enemy or similar left on your ship and you warp it's going to remain. The warp fairies do not whisk him away, but if it's a drone it will have no command drone bay so it will be helpless so your guys can fight it off without resistance.

Maybe I did not explain it well enough. I warped away with the breach drone on my ship. The next star was one of the boarding events where as soon as you enter I had a boarding party of 4 on my ship. Now the drone was no longer attacking and the boarding party was also stationary. They just sat in the empty room they teleported into and did not move. As soon as the drone died the boarding party started moving to attack my subsystems.

That's an awesome bug. Nice find.
