What's up with HUBZU?

[Pat Jackson]

I've read just about every post on BiggerPockets pertaining to or mentioning Hubzu, the online auction site.  Common denominator=frustrating and irrational.  I'm prepared for that.  

I've been watching two properties for a few auction cycles.  Property #1 reserve was met last week, was "under review" for a few days, and then reposted.  Property #2 was bid on, reserve not met, and was back on the auction block in 30 minutes.  A few days go by and poof, they're both off Hubzu.  Just gone.  I assume they were sold in some capacity, but there was no explanation.  

Is this common?  Should I expect properties on Hubzu to just disappear?
