This is the second time it happens to us, ALL users from version-test got wiped out overnight. We cannot find from where it is coming from in the logs.
We do NOT have any user associated workflow that could be responsible for this. Please help! We plan to move to production in Jan18.
Did you file a bug report? We need this to look into your situation. Also, keep in mind Bubble has version control, so you can revert your data if needed.
