I found a mod-breaking conflict that I think is due to the v2.5 changes -- fortunately the solution is extremely simple. It may be due to some other mod in my install that affects NPC dialogue, but the issue is new in the last 2 years.
Currently, Thalantyr's dialogue tree only gives you the "Rumors? Bah! There's no mage here that wishes to speak or be spoken of ... " state once. It used to appear every time you talk to Thalantyr. Thalantyr's Item Upgrade places its functionality within the "Rumors?" dialogue tree. The effect is that you get to ask Thal about making magic items exactly once, and never again.
Now, the "Rumors?" dialogue tree has a trigger that RumorTalkThalan=0. Once it triggers, it then creates the action:
SetGlobal("RumorTalkThalan","GLOBAL",1)
And you never see it again.
Until the mod is updated, you can go into THALAN.dlg using Near Infinity and change two Actions (6 and 18 in my install) to:
SetGlobal("RumorTalkThalan","GLOBAL",0)
That fixes it, but ensures that you get to play Thalantyr's coy little game every time you talk to him once more
