Interesting Multiverse bug/interaction

This is an interesting, unusual and somewhat improbable thing that happened to me while playing FTL with the Multiverse mod just now.

I entered a Pirate sector and fought the guard ship. Among its other systems, it had a teleporter. I was able to crew kill the ship, opening up the menu where you can choose between running a salvage mission and the other options. I chose to run a salvage mission, a "visit the colony" event that resulted in boarders on my ship. Three humans appeared on my ship - but then immediately teleported away to the empty Pirate guard ship.

I knew that if you kidnap enemy crew and jump to a new beacon where there's an enemy/neutral ship with a teleporter, they'll teleport to that, but this is the first time I've had it happen with an empty guard ship.

Has anyone else had this happen?
