Units 'bouncing' back out of a wormhole - why?

[ledshok]

Hit a slight problem in my current game. Trying to move units from one friendly planet to another but they keep 'bouncing' back out of the wormhole.

By that I mean right-clicking the wormhole (or tabbing out to the galaxy map and right-clicking on the destination system) the units all travel 'down' the wormhole (ie disappear) yet less than a second later they all come flying back out (into the system where they were travelling from).

Have never noticed this behaviour before. There are resistance fighters flying around on both sides of the wormhole (and travelling through it) if that could be a factor...

Thoughts? Something obvious I've missed?

Check if you have a redirect rally post on the destination planet.

Oh man, the times I've done this. Or the times my ALLIES have done this. I'm so glad there's a "ignore ally rally posts" option now It was driving me nuts.
