Ptolemaioi unit bug

[MegasAlexandros]

So, I started a Ptolemaioi campaign a couple of days ago and wanted to take Petra early. It had a full garrison, so I built up a full stack and besieged the city. Fast forward a few turns, and the AI decided to sally-forth and do battle. So, on the battlemap, I decided to draw up my forces in a formation and I wanted, but the pathfinding completely bugged out. It was as if each individual sprite didn't know where to go and just ran off in every direction. The AI also failed to respond to my orders. I'm just curious if this was just a one-time thing or if anyone else has experienced this problem? Petra also lacked any sort of wall around it, in case that may be a problem.

Am I right that Petra had no walls at the time the AI sallied?
This is an old Vanilla issue that hasn't been fixed by CA...

Giving the orders multiple times and maneuvering your army away from the city can help sometimes.
