Landmines in the gloomy caves shop

Has anyone experienced landmines in the GC shop?
A character of mine blew up the there (cascading wand explosions, and a wand of striking on the floor), and his bones will never be found.
Death message says he died of a landmine.

Pretty sure I saw one in there at least once.
Normally I'd say that this is a bug that needs fixing but on the other hand this fits IVAN too well.

I've almost definitely seen bear traps. Not sure about a mine

was it under an item? or was it on a blank space?

question, if an eddy moves over a set trap does it move it to a new location as set, or would it appear as unset at the new location?

Did a quick test; looks like they remain active...

More diablolical uses for Eddys

If you teleport an active trap, and it appears underneath a character, does it go off?

I guess it shouldn't, as when you set up a trap, you have to move away from its square and then on it again to set it off. So the game likely checks whether you move onto the trap, but not whether you are already standing on it.

can you polymorph into an eddy?
