Doemenel Manor, Gedmar Doemenel's study chest states it it s 6 Mechanics + 7 picks | 7 mechanics to open. My rogue has 6 mechanics and that tooltip is showing in white indicating the game knows I have the perquisites. When I click on the chest it does not open "Lockpick Failed. You need ...."

 

I can only assume that the chest is incorrectly labelled or that there's an issue with lockpicks only stacking to 5 in the rogue's inventory. I have 3 stacks in their inventory and more in the stash so it's not a shortage of picks as a whole.

I am also having the same problem. I've saved in the room and am hoping patch 1.03 fixes this issue.

Unfortunately, patch 1.03 did NOT fix this bug.
