Overpressure plug blew

Hi all, has anyone experienced this? I was just canning chicken broth in my pressure canner, and the overpressure plug blew out, releasing all the pressure. I lost a good 25% of my broth.

I had previously removed the plug to use the canner as a water bath, so maybe I didn't have it in right. Or maybe the pressure was too high. The presto manual says to not use the canner until I call them (not open until tomorrow). The plug doesn't appear damaged at all.

I was wondering if anyone's been through this? Did you have to replace the plug? Should I assume the lids are no longer suitable for sealing?
