Something has changed in the pathfinding code and not for the better. In beta 3A ships were pretty good at working their way around obstacles but in beta 3B the ships seem to have reverted to an earlier algorithm.
Colony ships now go on a straight-line path towards their destination and if another system happens to line on the line between the begin and endpoints then the ship stops in that system and asks whether you want to colonize the system.
Warships and Colony ships are now stopped by anomalies in their path, you get the pop-up that states that only survey ships can explore anomalies, rather than the ship going around the obstacle.
