Summary​

Game and computer blocked in full game

Description​

Big problems encountered during a game completely preventing me from using my computer.

After about twenty hours of play on a game my game begins to freeze completely and then return, the game continues until the moment when the stop blocks completely and prevents me from doing any action (alt +f4) ormis turn off the computer by holding the power button.

This problem has been going on for several months and despite an email conversation with the Paradox team and a few attempts (reinstallation, deletion of files, DXDIAG, checking various files) no solution was found.
Paradox suggests that I post a message here.

A message appears on the error log:

10:48:57][E][jomini_script_system.cpp:284]: Script system error!
Error: has_same_culture_heritage trigger [ target culture was null
Script location: file: common/schemes/scheme_types/learn_language_scheme.txt line: 150 (learn_language:base_success_chance)
file: common/schemes/scheme_types/learn_language_scheme.txt line: 93 (learn_language:base_success_chance)

and Paradox advise me to ask the developers for help

Thank you in advance for your help because I would really like to be able to enjoy this game with the purchased extensions
