Can anyone please explain how this Zone of Control situation works

[Displacement]

As Morocco I and Grenada are fighting AI Aragon and France. France marches an army from Badajoz into Evora and then into Lisbon, catching my recovering stack off guard, and seeming to waltz right through my zone of control from the fort in Beira. This is one of many times that it seems to me that the AI cheats ZOC rules, but I just can't tell because they're so damn confusing. Can anyone help?

Also can anyone explain why we threw a shit fit when PDX made that incredibly simple and cool ZOC revamp?

Return province is Badajoz. Beja is a non-zone-of-control province - so the distance rule allows movement into Lisbon from Évora.

By no means is it a rule that you can't go from one ZoC province to another. You can, if there's a path from the return province to the destination through 1 or 2 non-ZoC provinces. Or a few other times, according to the other rules.

This is a situation where the ZoC algorithm defies all logic. Sorry dude. But yeah, IoaanesBarbarus nailed it.
