We've released a game update for Total War: Shogun 2 which includes,
 
↗️ Compiler upgrade - This is an update for the game to better use modern architecture and improve performance.
🖥️ Fixed game crashing when running on CPUs with more than 32 logical processors

Alongside this, as the current chat systems in our game are both antiquated and limited in the modern online era, it is necessary for us to remove those services from Total War: SHOGUN 2 and our other legacy titles. We are, however, continuing to investigate ways to implement and support chat in our future projects properly and will keep you updated on any future changes or developments. 

Thanks for your understanding; if you're looking for a free chat option, you can also visit the official Total War Discord server to chat with your friends.
