When playing the new Build 64498 units leaving factories that have been line built appear to move behind the factory before moving to a position close to the rally point set. Alot of the units continue moving around even after getting close to their destination. Could be a bug with formations. I will try testing it with separate factories and separate rally points. *update* The bug appears when the rally point seems to be blocked by other units or wreckage. I guess the units pathing gets messed up somehow? Line build or individual doesn't appear to matter.
Also have some weird rally issues. Units tend to go a completely different direction. Also air units seem to go under the terrain at times.
