Two problems I encountered.
I had to add the Apache tribe to stop a load error (missing swordsman) I was not using the Apaches in my game but was using other North American tribes. Also as I was using the Maori tribe I had to also add the Polynesians. (Unit-Artstyle-Polynesia)
EDIT.
I also loaded a new Large map with 10 Civs, No Rev or Barb Civs. On the first turn.
Unmoded memory usage 667,272k, moded memory usage 654,412k. A saving of 12,860K.
