Having played each of the games three times through, I have been able to do romances in all games with various characters.
As after this patch am still unable to trigger paramour III.
I have loaded saves prior to (more than one of each) romances in all three games, made post-patch saves both prior to and after viewing the relevant scenes.
Still nothing. I have done this at least twice for each game, in alternating order. Nop.
Additionally, the in-game achievements accessed in each games menu are now even less accurate than before - ME and ME2 show me with paramour and paramour II (this is accurate) although various other medals are now grey that shouldn't be - ME3 only shows Paramour I.
Not sure of any other way to try unlocking this at this point.
Just to add my situation (Xbox One X) - completed ME2 on Insanity and romanced Garrus but no achievements popped retroactively for me. As I carried on playing beyond the end (to complete the Shadow Broker DLC) I no longer have a save for prior to the Suicide Mission.
I'd previously completed my ME1 Insanity (achievement popped) and completed the romance too (again, popped). I've gone into my ME3 run but am a little nervy about not popping at the end of it!
Not thrilled at the prospect of "just playing it again" tbh!
