As HOPr of Beogh I gained Saint Roka as follower. In Vaults he got banished (I don't know how, but Henzell-bot reported it. There was a Zot trap in the level). Then, in Hall of Blades a distortion weapon banished me. I found Roka in the Abyss and he followed me out. Now the distortion weapon hits roka and he gets banished again. Later after abandoning Beogh I enter Abyss in search for the rune. I meet and kill Saint Roka twice.

Did you teleport or experience an Abyss shift between those latter Roka sightings?
