ToME: the Tales of Maj'Eyal

I am playing the beta as a ghoul shadowblade and I sent my shadow "ambuscade in with shadow step and veil of shadows" and it beat him to the point he offered to destroy zigur and this lua error pops up when he says it is time to go and I cant get out of it so I am stuck.

I think it is because he is talking to my shadow and not me, I am hidden behind some trees and he has never seen me...
