I'v updated to the latest beta since this happened but twice today party crashed with it's own internal error and a message popped up saying to log back in. I did so and got he same error.SO I restarted the comp and opened party tables, when I turned on auto import the party error message came up straight away. They were HU tables and I was the only one sitting.
I didn't see any mention of fixing a party bug in the release notes so I thought I'd post. Still waiting for action but I'll post if it happens again. If not there is no problem anymore.
