Pawns don't rush base

[Elixiar]

Attacking pawns don't assault the colony and instead stand still as soon as no path is available to a colonist.

Even if one enters reachable space the invading pawns are 'locked' in place almost indefinitely.

Help?

Thanks.

Can you provide your world map and save game which demonstrates this (zip them and attach them to a post)?  Without actually seeing what's going on it's hard to say.
