Well, as of version 0.94, I'm still running into that freezing bug in the bridge mission; and unfortunately, this last time, the game didn't seem to produce a log when it went south. :-/ In case it matters, I'm guessing that Ebon Raban is trying to charge his target when he's attempting to make his move (which is when the game's been freezing), but since there's still water separating them, he won't be able to reach them. I've seen those "can't reach target" messages in earlier playthroughs, but they haven't caused the game to hang up before.
This last observation isn't exactly a bug, but it's been happening pretty consistently to me since I started replaying this mission: almost every time that the Ebon engineer places his charges on the bridge, another Ebon character has been caught in the blast. It's usually a cavalier that attacks the charges before a mentalist or crossbowman has a chance to finish them off, although this last time, it was actually another mentalist who hadn't taken his turn before a different mentalist used gravity spike on the charges. And while the cavalier/mentalist who's caught in the blast has always survived the explosion, he's never able to swim out of the water after falling in, regardless of how much energy he has. While this is kind of amusing to watch and it's sort of doing the player a favor, it obviously isn't very realistic that the bad guys would so blatantly damage their own forces; but I don't know how much of a priority realism is for you at this point, on the eve of the release. Those are just my two cents.
