Started a new campaign post 1.0.1 updated, unmodded, files verified. Same crash occurs (compared the exceptions and stacktraces, they're identical) but this time it occurred after starting then breaking a siege, after several game ticks. This makes me think that the issue is not an issue with clan members joining the party, but rather an issue with the game processing background events (like battle autoresolves). Crash occurred after less than an in-game day of time without fail regardless of what I did in the interim between loading the save and the crash.
