ToME: the Tales of Maj'Eyal

My PC is in Ruined Dungeon, killed 5 guardians, 1 disappeared. There is a 3x3 area on the map where it is hitting me for 23 damage every turn, but I can't hit it back. Earlier there was a void horror in the room with it, and when I came back it was also gone, perhaps it had something to do with this.

Twice in my current gameplay I noticed enemeis that cannot be seen or targeted, but which are hitting me for damage. They also couldn't move to follow me.

One was a slime in the sandworm tunnels that was either hitting me in melee if I moved to certain tiles or doing some ranged attack, the other one was a wight in Dreadfell, so both were no guardians.
