Access Exception - Client Crash on LUA: [C]: ? [C]: in function 'GetItemComparisonInfo'

This seems to happen in random new Quest and Quest completion dialog and depends on the rewards and the equipped items. The crashing makes questing older content unplayable on the current version. I updated video driver, scanned and repaired, cleared UI caches, zero addons. The problem seems to be a bug in the LUA scripts / a data issue.

I also tried unequipping all items on the character in the reward item slots before bringing up the dialog but it still crashed when the mouse hovers over the reward items. Seems like it is most likely a problem with the quest reward items based on that.

This happened to me on multiple quests in Borean Tundra.
