The Retreating AI can walk through enemy units?

[Proterus]

I was playing as Brandenburg and I invaded Poland and had my forces grouped up into separate stacks and I found the enemy stack and engaged it, I sent another unit that was going to arrive later, just in case the AI sends reinforcements or whatever so I win the battle and the stack goes into retreat straight into the path of my arriving stack and their paths cross and no battle occurs, he gets to walk straight through to safety, what's up with that?

Units with shattered moral get this little white flag on them, which means they're in "shattered retreat" and cannot be intercepted. Its part mechanic to avoid gaming the AI and part RP.

I think blocking a strait on a retreating army's path will stop them, though.

Yes usually this will block them, though the exeption is that they will not get blocked if the retreating nation owns both provinces connected by the strait crossing.

You cannot engadge a shattered army until it reaches the province it decided to retreat to, forts do not stop shattered retreats but blockaded straits and mil access do.

It happens to the player as well as the AI if you lose a battle.
