Crash when being ambushed at the battle of Guangling

Build: V1.0.0 Build 9198.1663030
Description :I've been playing a campaign and got ambushed. When I try to fight the battle manually the game crashes. It shows a pretty odd map for a ambush map before it crashes so I'd assume it's loading a weird crash.
Reproduction Steps: simply load the quick save battle and load the battle of Guangling, small city. It says small city even though it's an ambush.
Solution: If I just reload a previous save and not get ambushed it will fix it.
