Enthrallment of Bogis quest from completed to failed
 

Doing the frog quests in Marshon Swamp and after telling Squelch I'm putting the King's flag over all 3 of the frogs buildings I go to Bagaba and as soon as I put the flag over his building the quest "Enthrallment of Bogis" that was marked as completed in the quest log changes to failed.

I'm pretty sure I've done these without that happening in the last game I played. Anybody know whats up?

You have to finish that quest (Ie. talk to the middle brother) before you talk to Bogis about appealing to the oldest brother, otherwise you fail the quest.

Tried that, but same thing happens. Seems I've tried completing this series of quests in every way possible, which actually isn't many, but the quest still changes from completed to failed once you put the kings flag over Bagaba's house.

What King flag? i have made this 3 times and never placed any King flag? o.o
