XEEN: Boulders in the desert on Darkside still visible even after they disappeared
In Darkside, there is a riddle in the desert with some boulders that have you spell the mane of the former owner. The solution is "Paladin", which you tell one of the boulders. After that, you can re-visit the other boulders and each one disappears on interacting with it, leaving behind a piece of equipment. The boulders correctly disappear afterwards.
However, if you look at the boulders from another map area, they are still there. If you move one step closer, they will disappear
see save game (there are still some other boulders in the desert that still give the equipment. These can be used for debugging if necessary)
