Check-in issues

Unable to modify terrain - Severity: Critical

The issue:
Me and my team have been working on a project, unfortunately none of us can modify the terrain ( i mean we can but when we go to check-in the changes it doesn’t work and says the assets are being checked out by another member even though it’s not) It’s been happening since we made a project in our team.
If replicable, how: Be on a team with multiple people, then edit the terrain and check-in the changes. The error should eventually appear

Have you tried reconnecting with the session?
We had the same problem and that pretty much solved it!
