In guy rooms on screens outside of caves, if the room type is set to Red Potion or Heart Container, then the guy does not disappear permanently after Link takes one or the other, which means the red potion and heart container can be obtained as many times as the player wants. Example: https://www.dropbox.com/s/ijgejpg6nz...ytest.qst?dl=0
Note that I updated this file. By the way, this only seems to be happening with the red potion or heart container room type; it seems rather strange, considering that this does not happen with the take one item room type.
