Since 2.0 has come out, I have had not one but TWO worlds corrupt. We are on xbox and don't have any mods. This is ridiculous and making us long time 7 days players not want to play the game anymore.
Open the console and click the button to report a bug. Enter the details on what happened before it corrupted in the report. It is ok if you aren't able to access that world, they will get the most recent logs that should hopefully show the issue so it can be resolved.
