Well guess what, turns out you can use NearInfinity to edit your save file, and GAM is saved in save file! I found Tiax(showing as *iax), changed his location, and there he is in the zombie village!
SCS doesn't offer this tweak anymore, and Anthology also requires a new game.
I think I could write a simple script to spawn Tiax next to my character, but the original Tiax would still be inside Baldur's Gate. I guess it is a dead end. Thanks for your patient helps
I set him at the entrance of zombie village, but failed to make him appear, should I also directly place him on that map?
Edit: Tiax appeared in his new location in a new game, I guess you just have to do that to make things work
I'll take the risk, I'm still in chapter 1, so it wouldn't be that funky.
I want to move him to the zombie village, thing is, I can't find his reference in his original area(AR1100), now I'm stuck.
