I'm encountering the same. Clean install of public win64 1.0d, user data likewise cleaned, start game to repopulate user data, exit game, unpack the bugfix and expansion mods to the proper directory, start game, activate just the bugfix mod, exit game, start game, activate just the expansion mod (after bugfix mod in list), exit game, start game, CTD.
Log shows:
