Letter to Kafei can overwrite Pendant of Memories.

[ADeamore]

If the pendant of memories item is gotten before the letter to kafei, and then the letter to kafei item is given, it will overwrite the pendant. preventing the player from being able to do any checks required of that specific quest line. This bug softlocked a run i was having and we ended up having to use the console to give the pendant to the player on majora's mask.

Pressing your L input (A input works as well as of 0.9.5) while hovering over the quest item slot on the items pause screen rotates through the received/found items on that slot.
