Slightly odd one, this, and I’m curious as to whether any other players have encountered it. I was at the mote dunking phase prior to the final boss final damage phase in Prophecy on Explorer mode when for no reason I could see (ie. no “contacting server” messages or anything) some of the thralls and one or two of the knights just became completely immune to damage. They were not casting barriers to each other that I could see on screen. I was using Graviton Lance and Last Call and just got stuck for a while because I couldn’t damage the knight and get motes to spawn. Killed myself a couple of times and that seemed to fix it. Anybody else ever come across this?
