This should have been fixed in U237.3 but it doesn't hurt keeping it if you want to be safe

This mod potentially (funny I know) prevents your save file from being corrupted due to the social hub data being saved to it. Research done by multiple people led to the conclusion that there's a possibility that the names of your friends which are saved to your save file might cause corruption of it.
This mod completely prevents the social hub from saving any data. Unfortunately this also means it will not remember your "favourite heisters" or blocked users but I'd argue thats not as big of a loss as your entire save file.

Clarification: If your save file is already corrupted, sadly this mod will not help you. It is only meant to prevent the corruption happening in the first place.
