Strange CTd and a ghost General

[GMT]

Did you use move_character to teleport that general? If you teleport him while he's still inside a city then he disappears just like you described.

As for the revolt, have you tried to lower the population of that city? This can improve public order and if this doesnt help you can take control of the Getai and use process_cq and fix public order yourself.

You can find the exact procedure in the frequent issues thread look for The game crashes as soon as I end turn / The game crashes during the AI turn. section.
