We fixed out weird "bug" in code, now everything working as should. You need to update your wallets and nodes. Also we extended maintenance window for another 2000 blocks , so reward plan adjusted. You can continue mining on umine.org - they updated properly, thanks again them to support during investigation of this issue.
