I had one instrument destroyed and another significantly damaged at a music camp--both had been in an instrument room where I'd been led to believe they'd be safe.

The damaged instrument had been grabbed by an eager non-musician when someone asked for a guitar--I tracked it down and unceremoniously took it back, which ended an impromptu jam session.

I have no idea what happened to the other one--when I retrieved it from the instrument room, the case rattled, and when I opened it, I found that the instrument had been smashed into small pieces. That was the last time I went to music camp.
