I'm experiencing the same thing
Game Version: 0.92.63 and 0.92.75
Bug description: LowLevelFatalError [File:Unknown] [Line: 42] FMemoryWriter does not support data larger than 2GB. Archive name: None.
Context: Crash occurs during manual and automatic saves. The save file is corrupted, the file can be loaded but the game state causes an immediate crash.
Reproduction Steps: Loading a save with extended play time, running the game for a few minutes, building additional buildings, and attempting a manual save reliably retriggers the error.
Repeats after loading a save: Yes
