OK, fixed - the 279.89 SP is now properly saved as delegation and the invested STEEM is at 353.409 (409.955 SBD was sent). Please feel free to test it with status or refund commands. By the way, no profit was lost because at the time when the error occurred, @tipU was recovering voting power (and still is).
Sorry for that, seriously - just when I went to sleep there was a power failure which took down the service server. This caused few errors (see comments above) - just when the post hit trending and new delegations came. Thankfully, because of the transparency and @tipu confirming every delegation / investment it's easy to track the errors. Just didn't have time in the morning to double check everything.
No problem at all. And I am really happy for the your support and effort. Thanks indeed.
