Published products suddenly are changing to drafts

This is a huge problem that began yesterday. I think I did an update to marketpress but two different clients on the network and two separate products.

I locked the post and republished so I was the only one who could edit or change them...they were fine until just now I got a call from my client that the same product I locked is now in draft again??!!??

Anyone else experiencing this? Anyone have any clue how a ghost is changing published products to drafts that are unpublished??

PLEASE HELP! This is a serious problem...
