Dedicated servers are having issues where they will suddenly hit a save error denoted by the [CRITICAL] Failed to Save lines, and then not work anymore. When new clients try to join, they are stuck trying to load forever. Currently connected users (upon successful reload/rollback) find that their character is lost and are returned to the character select screen. Both server and client log attached. Logs are for DST Creative Mode (modded), but I have seen the issue happen on fully vanilla servers.
Leave a server online / running for a long while potentially? Unsure of how to repeat.
