I'll have been here 4 yrs next month and I've played everything there is/has been. The firenode and the Balor has been the biggest hassle for me. CTD's, corrupted saves, you name it. I've beaten it numerous times with no problems. I really don't like the nodes and I don't play them anymore because of the hassle and strange things that happen. Way too many bugs that wont ever be fixed.
Heh, I joined a month after Razgovory. We've presumably posted about the same number of times then Thats an old bug too. Often happens when you are trying to get into position to spank a Temple party: you're just maneouvering Meleny to her fire support point and suddenly they all go berzerk.
Yeah, I've had this happen too. Basically, making sure your party NPC's are nowehre near the Temple NPC your "face" PC wants to talk to, stops that problem. Taking the time to move party members manually beofre initiating dialoge works, if you have the room to do so.
