Your address is stored in database as 15oFYM8oC32ZTWwcDRrUM4OSfy2KzoWhgK instead of 15oFYM8oC32ZTWwcDRrUM4osfy2KzoWhgK. There's uppercase “S” instead of lowercase “s”.

I made usernames case-insensitive for website/display purposes, so you can view your stats even with all uppercase letters in your address http://clevermining.com/users/15OFYM8OC32ZTWWCDRRUM4OSFY2KZOWHGK - but the actual address stored in database is the one that you first started using and your user was created with it.

It seems you entered a wrong address, as the version with uppercase “S” is not a valid bitcoin address and this is why payouts wasn't sent to it. From what I see, you've been using the wrong one for 140 hours and corrected it to the correct one only 5 hours ago.

I changed your address in the database to be the correct one. You should get your payout in the next batch, probably in half an hour from now.
