Re: Character from Awakening will NOT load into The Golems of Amgarrak or Witch Hunt
Shouldn't be any problems importing your character from DAA to GoA.
I've done it many, many times.
Did you have any mods running when you made your last save in DAA?
The "unable to load area" error is often the result of having a mod in-use when a save was made, but having removed it (or otherwise made it not available) since then.
If you had any installed, you might try removing them, loading the last save you can, playing for as long as you need to make whatever plot-point decisions you want, (side with Architect, or not) then making a NEW "last save" and importing from that one.
Let us know how it goes!
