Weird issue with the Transmutation Seal - sometimes it simply refuses to work on walls. Any walls, no matter how many times I click on walls while it's active; it still works normally on items. I
think it might only happen right after using PISORF to push a monster into a wall, and the problem might also go away if I do something else like attack a monster, but I haven't been able to test it enough to be certain.
On a related note, trying to use the Compression Seal on an item that is consumed when used (Orb of Zot, Amulet of Yendor, Badge of Honor) will cause the item to be used and consumed. Same issue with glyphs, although they're obviously not consumed.
EDIT: And
this just happened when I tried to use a Transmutation Seal on a Badge of Honor.
