I don't know if this is the right section to post this, but you do have to get to tier 5 Romulan Reputation to trigger this mission.
I am on New Romulus doing the mission in the underground ruins. When I get to the last section where I have to defeat the Tholian Captain (after shutting down the power plant) he keeps jumping over the railing into the lava area below. I can still see a red enemy dot where he is, but I cannot target him or jump down there. This has happened repeatedly and I am unable to complete the underground ruins mission and get to where I can signal D'Tan because of this.
I need to do this mission to complete the Romulan reputation, but this glitch it making it impossible.
Has anyone else had this problem?
I sent in a support ticket, but the last ticket I sent in about another problem I am having has gone unanswered for over a month now. I don't have much confidence in the Cryptic support team and wanted to know if this is happening to others.
