Funcom doesn’t do rollbacks often, in-fact it’s about as rare as a unicorn and must’ve been the last resort to fix something. If your server did actually rollback, it’s likely because the server itself crashed, when it tried to reload the game database it found it was corrupted and unable to load the game. If the server is unable to load the database, it will keep checking the backups one at a time until it goes back far enough to locate a database that can be loaded. When this happens all players will lose time, not just one player and it won’t show up in the logs. I suggest checking the server logs to see if anything is listed.
Quick question - You’re playing on a PvP server and find the notion of losing everything and having to start over as off-putting? If so, you might want to rethink which type of server you choose when you do get started again.
