Summary​

Game crash without user interaction; log shows Diarch Imprison failure issue

Description​

From a savegame of 10 August 1155, game crashes on 13 August 1155 without user interaction, after game unpaused. Last entries in logfiles are about Diarch Imprison co-vassal failure. Presumably for an AI diarch, as player character doesnt have one.

Steps to reproduce​

Unpause game from my save file, let it run, game crashes after 3 ingame days, regardless of player behavior (9 times so far). Sadly the Crash Reporter fails to upload. I have the files: 50M Last_Save.CK3 and 41K minidump.dmp plus the smaller log file.

Game Version​

1.16.2.1

Platform​

Windows

Enabling Betas in Steam and selecting game version 1.16.2 allowed my game to progress past the date which causes a crash when on 1.16.2.1.
