That's the same what happened to BOSTASH, it's easy to reproduce. If you use summoner quite before resting in an inn, you'll get a summoner and full mana after resting, but it does not work if you rest somewhere, where you have to stand up first, like in icemist underlevels or where you meet Hirge first time. Than you'll be stucked and it's not possible to stand up or do anything.
