This happened to em the other day and again just now. I was in Vivec, I fell over dead, I wasn't killed I just died. I got revived by another player and I son as I accepted the rez I died again. Again I wasn't killed, I wasn't even hit, I just died. My screen says Revive (E) Here, Revive (R) Wayshrine like when in PVE but neither option works and I can't be revived by another player. I have to relog to play again, which likely means an hour or more queue for CP campaign. This is the second time this has happened to me since Morrowind, please fix it.
I use to be a PVP'er like you but then I took a lag spike to the knee.
