Thanks, we are looking into it 
Well units give up their formation (and therefore block each other) when:
- stop button is pressed
- click on enemy unit
- attack move
So this actually looks like intended behaviour right now. Maybe attach a clip and I can see what the issue is
The clip was attached - Investigations into Pathfinding - #32 by NotSure
Maybe I shoud’ve posted that here instead of bug report? Not sure – well, here’s the link here, in case
Thanks for your report, we are looking into it
I decided to report this moment as well. Usually, bad pathing means units can’t find a path or bumping.
But here the opposite happened - units ghosted through enemy units without any interaction.
I know, that it can be more or less intentionally used (abused) and is somewhat skill dependent. I have never had luck consistently moving units in specific patterns like other people do, but I believe it should not even be part of the game at all. It’s highly unpredictable from enemy or your units and ruins balance.
Moment at: 20:20
Replay and clip attached.

Playing Tariq ibn Ziyad campaign mission 5.
Around ~1:14:00 A castle is destroyed at the river crossing. At 1:14:16 the foundations despawn and the pathing behaviour seems to change. Some units can path through the gap in the wall, others chose to take a long detour to a different shallows to cross the river. ~80% of units path through, new units all chose to path around rather than through the short path. Move commands to take the short path are ignored. Destroying the gate solves the issue.
