So... I have been trying to get Izanagi’s Burden by completing the lock and key questline. It worked fine at the beginning (got 2 keys and compleatet the kills on the leviathan) but ever scince the halloween event came out I cant use the keys on the box anymore (when I use a key it just disapeares and the box dosnt get any progression). I even restartet the complete questline because I thought it was some how broken, but even after restaring the quest I still can use them. Is it because of the halloween event??? please help :(
