I have seen this a couple of times: when Lord Rat replaces a player who has baubles, it froze when playing a bauble.
That bug seems to have slipped throught the cracks of what to fix before the release. Sorry for that. :(
Looks like this bug is already known. Since I came over here looking for answers, I'll add a "me too". At least now I know it's the Bauble that caused the problem. Thanks.
