Terl spawning again waaaaay after Ano having his test is as it should be in the original game, yes.
- first, Moira gets murdered and Ano hears about it,
- then, Ano gets to choose, suppose he does a good choice and doesn't touch Saerk,
- then, romance progresses,
- at some point, Ano is summoned to to his test, he becomes a knight,
- as a very 'knightly' action, he offers to bed PC, then, at lovetalk after next, confesses his undying love(wrong order, but never mind),
- finally, Terl spawns again, and here Anomen should run off.
First of all, do you have FlirtPack installed last? It should be, otherwise Anomen's J file is in trouble.
I thought maybe this was a new development of the mods, but instead long after Ano has had his test, Terl spawns again, and Anomen enters into a constant dialogue loop repeating the flirt about 'earthly pleasures' over and over again.
Instead of "One approaches, and his appearance seems familiar to me?" Yes, sounds like a problem. I'd temporary disable flirts via console - I think there should be a DisableFlirts variable(not sure about the correct spelling, however).
