Bugs not mentioned on the DevTeam's website Edit

NameStatusDescription
The hero can teleport on a non-teleport level: Get engulfed by a tame engulfer using conflict, end conflict, apply a magic whistle.
It is impossible to paste (e. g. "ElberethElbereth") into the windows tiles build. This works on OS X, however.
The game sometimes behaves as if a series of spurious non-attacking movement commands were typed after #looting a container.
Confused #looting a throne does not destroy it.
The "highlight_pet" option does not work on monsters only seen due to the monster detection spell.
