Every couple fights I notice a unit stuck in an endless loop of skipping a turn. I might be wrong, but I feel that AI gets really confused if it isn't able to attack someone this turn. 

Same feeling here. Strange behaviour of unit not moving, not trying to get closer to my team.

Yea I especially noticed this at the first fight upon entering the dig site.  The young boars did not have a path to get to my characters and basically just sat there the whole fight skipping turns.

Same thing happened to me. I was on the stairs and the young boars could barely touch me. There was a large boar also that died miserably without doing any damage.

This happens to me a lot in ship boarding but it's always been my crew that have the issue. I usually have one AI crew just skip all their turns.

Thanks, everybody! I think we'll have a fix for this in v4.1.1.
