Stumbled upon a minor bug. I am unable to throw stuff through an open secret doorway by picking it up with the mouse pointer. Can't be thrown whilst standing directly in front of the open doorway from either side, inside or outside. It works if you stand further back. Shooting from sling works, but not picking stones up with mouse and throwing by holding them in mouse and clicking on screen. Can anyone else confirm this?

Which level is this?

Tried it with another secret door on same level with same effect.

Seems a fix you implemented earlier to prevent the discovery of closed secret doors backfires. Now nobody can throw when facing a secret door, no matter if open or closed.

Also discovered something similar:
While standing on the same tile as the statues on Shipwreck Beach throwing attacks send nothing to the air. Any projectile goes straight to the floor.
