Answer 1

I am working in VS2015 with an integrated Perforce p4v client. In my case Perforce tried to add moc file to a depo, when I reverted this operation, Perforce removed this moc file from project and deleted it. The file was recreated after the next compilation, but it wasn't included in project, I have to add it manually to Generated files, when I finally understood what was the problem.
