RESOLVED! Only took a month, but I figured it out on my own. If you are withdrawing BTC, make the request, and wait for no email to show up, as usual. On the 51BTC website, when you are looking at your withdrawals page, change your language to Chinese in the upper right hand corner. Then when the page changes to Chinese, try to remember where the "Recheck" link was next to your request. Click the Chinese characters for "Recheck" (重新验证) and you will finally receive your confirmation email.
Hey Dallski - great news and well done man. I know what it's like to have some coins locked up somewhere and not being sure you'll see them again, not a good feeling. Glad this worked out for you.
@asdf55 - I think you're right with the bouncing - I know block times vary but didn't put the two together. I'm going to point your messages out to the coin devs and see if they have any thoughts to share.
Cheers,
M
