Unfortunately I'm not surprised. We're running a pretty outdated version of phpBB, and there are a bunch of things that haven't worked right for the past few years (editing buttons, emoticons, a few other things I've lost track of). I'd love to see all (or most) of those things get fixed, but the problems don't seem to be a priority for the current owners. :-\
I hope they're at least doing frequent backups...
