I have so far only played and encountered this error on multiplayer. This used to happen in the 32 bit 1.66 version and now still happens in the 64 bit 1.68 version. Although in the basic.rpt it says process 64 bit False.
Launcher version: 1.5.140900
Game version: 1.68.140908
Branch: main / beta branch not specified
Sometimes I can go 12 hours playing this game without a crash. While other times I get this error in 1-2 hours on the same server.
