Dialog bug ??!

I was asked to create a thread about this problem:

http://www.shsforums.net/topic/47635-notes-oddities-and-possible-bugs-in-my-bwp-game-spoilers/page-39#entry581038

Imoen and Breagar stop moving all the time and keep looking at each other as if they want to initiate a dialog.

I used LStest and this message keeps repeating: "Block 48 of ACBRE.BCS"

block 48 of ACBRE.BCS
		PlaySong(115)
		ActionOverride("imoen2",StartDialogueNoSet("ACBRE"))
END

IF
	GlobalGT("CHAPTER","GLOBAL",1)
	InParty(Myself)
	InParty("imoen2")
	OR(2)
		Global("ACBreImmyActive","GLOBAL",0)
		Global("ACBreImmyActive","GLOBAL",2)
THEN
	RESPONSE #100
		ActionOverride(Player1,DisplayString(Myself,152002)) // Running

Since my knowledge about modding is zero I would appreaciate it if anyone could help me find the solution.
