Not sure if this is helpful, but figured maybe someone in SD could dig into this autosave file and trace at least one cause of those frustrating CTDs ... if the CTD occurs on more than just my machine, anyway.  I've reloaded, re-attempted, even re-booted and re-loaded to re-attempt the action that generates the CTD and it occurs every time.

Select my Sovereign, Londikin, (first unit in the units list) right next to Acanachluy.  Send him one square east/right (if looking top-down) around the town so he is one diagonal square from Cuessusaa, the Level 1 Merchant Master heroine.  Attempting to cast Imbue Champion on her causes a repeatable CTD on my machine.

My computer is a custom built machine, Phenom 9600 (Quad core AMD chip) running Windows 7 64-bit and 4 GB of RAM.
