Someone did that to my whole project. I had catefully migrated all the source control to a new and improved system. Out boss decided which project went into which organization.
Some idiot went and intentionally deleted a project I was meant to do maintenance because he had decided all by himself that it wasn’t meant to be there.
I had to do a long train ride to the idiot’s office for a training and when he told me what he did (proudly!) I gave him the sort of verbal bollocking I have never done before or since.
To the point where he contacted our boss to complain. I got a call from my boss to excuse himself on behalf of the idiot.
