Mine also appears to be related to merchants. I can talk to NPCs, open my inventory, go anywhere or enter combat then save just fine, but as soon as I go into the trade/barter screen and exit, even without actually trading anything, saving will cause a crash every time. I've tried with every vendor in the druid grove and all have the same effect. I've cleared my LevelCache folder, switched engines and disabled cloud saves, all with no effect on the result.
