Since the new patch was deployed I have had consistent issues with the Riverhold area in Northern Elsweyr. Specifically the game will either crash, or lock up so hard that I have to reboot my Mac. I've tried all the tips for Mac users, deleted cache files, changed video settings, and rebooted but the issues persist. The game crashed 3 times in less than an hour last night and it was all in the Riverhold area.
I used the exact same Mac to run these same quests in a previous version of the game without any issues at all (less than 2 months ago).

Anyone else having similar problems? Anyone with advice?
