Ice & Fire: Marshan Swamp Bug

[Stanza]

Hello there,

I'm enjoying the game so far except for a couple of things. I'm doing squelch's quest who asks me to deliver an artifact to his brother Bogis, thing is the latter doesn't have any dialog option concerning this, I can only say goodbye when I talk to him. Secondly the Furious Paladin is still there in his castle, and talkative even after putting him in the Ice Orb.
I guess this questline leads to more necrolizards available in shop, so I'd like to know if there is any workaround.

Edit: I succeeded in triggering the next part of Squelch's quest by editing the savefile. The two brothers are now reunited, but when looking at some files, I saw references to a contract quest on Squelch's head (not too surprising). But I wonder how does one trigger that quest?
