Here's a list of all the elements that the engine won't let be built under the player:

Broken wall
Fluff
Gel
Image wall
Mud
Secret wall
Tar
Wall
Wall (hard)
As you can see, the list is a little... thin. Every other element can be build beneath the player and monsters without any problems (no beeping or crashing).
If we use the "
Build"
command instead of "
Build marker"
, the list of elements includes Pit, Image pit, and Water. Again, there doesn't seem anything buggy with this behavior, it just looks weird.
