Key duplication for the Musical Gate

I tryed picking up multiple keys at once without interacting with the gate. When picking up the second one, it seems like I only carried the second one with the first one disappearing. It didn’t let me pick up the third one tho. So I inserted the key I was carrying and when searching for the first one, I found two of them at the key spawn point.

After inserting one of them, the insertion animation didn’t seem to finish with the spot for the key still open, but after inserting the third key as well, the gate opend up normaly and I have one key to spare.

Edit: Tryed to do it at a different musical gate again, but ended up finding a second way to dupe keys: https://youtu.be/-Yjw4Ni9S8I Here I died multiple times during the ambush infront of the key area, but when the key mob got pulled out by the sword effect, it spawned a new one every time.

Had some other struggles afterwards, but those shouldn’t be a problem if the initial bug is fixed.
