I was in immortal citadel and 2 (possibly 3, but at least 2) potions appear to have dropped on the dais.
they were inaccessible. i couldn’t pick them up directly and they would not auto-pickup.
yes, i was in the middle of the fight , but i went by them several times.
i died, because i couldn’t get potions. started the fight and the exact same thing happened.
i finally got a clue and made sure that i kept the fight away from the dais.
this is the first time i’ve run into an inaccessible item like that. i have had some items not respond to auto-pickup, but i was able to pick them up manually.
