Encountered a softlock in the Royal Training halls, the receptionist had some how left the teleport room and was stationed in another corridor and the teleporter kept saying it was out of charge. Thankfully i had a mushroom in the inventory and eating it teleported me back to the dungeon.
The teleport started working again, i could then teleport back to the training halls and the teleported worked again there as well.
The issue happened after getting the sold gold band, speaking to the trapped princess and exploring every other room to try and find a way out with no luck until i tried the mushroom.
