With the recent patch, I managed to load my Zon, but once I put in a couple of hours, she no longer loads. Probably has something to do with the items.
as a temporary solution, please try updated mod data: http://mxl.vn.cz/kambala/sigma-1.1.zip. If your character still crashes with it, please send me the save.
known bug: some necro skill icons aren't displayed.
