I do not know if this will help, but ill leave this here anyways. This bugg seems to have been in the game without a fix for a very long time, which is unacceptable BTW!!
Me and my freind played through the game swimmingly, untill we got to the door of the source temple. we didnt have all the inherit stones so we gathered 14 and thought this would be enough. ofc we didnt get through, and after some googling we found out that its the homestead portals that triggers it.
Problem is, zixzax is just standing there, telling us to jump into the portal and see whats inside. we have all the portals in the homstead except two. The last one we unlocked was either the trading emporium or the armory. either way we are stuck.
I just can't grasp how such a huge gamebreaking bugg is still left unattended to. There are apperantly loads of people having trouble with this, and it leaves me with a taste of disgust towards a game that i would outherwise love to death.
