#edit again: it cannot be in block explorer yet

lets wait some minutes to get the block into the explorer
Ah, OK. Our posts crossed!

yeah.. just got a fresh copy and there is no 77 EXO. At least it is a good thing that it vanished in your local copy (of course it would be better if it had been processed but at least it tries to present the real situation )
Lets see if the 78 will come across or not
Nope, the 78 just vanished too. I see a lot of "*BLOCKED->THROW AWAY*" in the log, has it something to do with this?
