ToME: the Tales of Maj'Eyal

Not sure I'm not confusin anything, I'm not stoned at least, but...
I visited first floor of one of the pride (necromantic one if it's matter) then user Rod of Recall to store artefacts, then returned to global map, entered that pride again, and looks like it resetted.
So, is it possible and this is a known bug or am I stoned?

Its a commonish and known bug.

Thanks HousePet!
Do you work on some mod or addon or on improvement to something done before btw, as I can't ask it in chat?
