I'm currently trying to do the "Lock and key" quest step for the Izanagis Burden but it's not letting me finish it. I got all four keys required by doing the four forges at max temper, inserted the keys into the box and it only counted progress for I think one or two (This was before the fix). After the patch, it ticked three out of the four boxes so now I can't get the key I'm missing to drop again because i've already gotten it in the past. Abandoning the quest and picking it up again wont do anything because it saves my progress. What can I do to complete the quest?
