I guess the thing is it doesn't seem consistent with what I've witnessed. Boffs in my experience have trouble navigating door - walls, even if the walls are hidden at some point in the mission. They just get stuck in the door. If pathing were just ignoring them you'd think they'd just jump through.
Yep, there is something deeper here. Perhaps a fundamental flaw with pathing that has never been found. Or, if it is known, it's never been handled. Maybe this is really the true reason that Cryptic's corridors are the size of cargo bays? Just speculation.
