Anybody else experiencing this glitch?

This one has been around for a while, and has been talked about on here before. No one knows what causes it, as its random characters and random buildings it happens at. The only thing it has in common, is there are always allot of people in that one building. EA hasn't stopped it yet, cause i don't think they know what causes it, or its a small amount of people getting it so they don't care.
