Realmwalkers,
We pushed a minor game hotfix this morning to address chat logs occasionally disappearing on players. There are no other updates/changes at this time, and while you are able to access Online Mode without updating, we highly recommend updating to get the fix for both Online and Offline modes.
You can check if you're on the latest version in the main menu, which should now be 0.3.1b.278384.
Thank you!
