I tried to get into Temporal Sanctum, and remembered I didn’t have the Unique on me that I would try and modify if I got to the end - But I had put the key into the slot, but not pressed the button to continue.
I closed the window and went over the to the Chest and picked up the item - But now neither myself or my friend can enter the dungeon door as it gives the error [LE-67] Dungeon Entry Door is already in use. (And my key has gone)
So I cannot bring back the screen to enter, and I’ve lost the damn key that I did have to gain entry. It’s bad enough trying to get keys as it is, but to just lose them due to hiccups like this.
