Logged workout missing

I logged (at least I'm 99% certain I logged) a short workout last night, made some comments and posted it.  I'm very certain I saw it in my blog after posting it.  Now this morning it's gone.  The "workout" was really just a 10 min spin around with some new equipment, so I'm an very unconcerned about losing data (I could afterall just relog it tonight), but I'm just mentioning it in case it is a bug.  Or maybe I screwed up.  Just wondering if you can see what happened/if it was a bug or user error.
