Ok, I try to write the final message...
blocks already mined before announcement, even 2 blocks are too much! Node doesn't work, explorer neither (up and down), if you stop the daemon you must rebuild all database and if you type "yes" your linux will show you a looooot of Y but no rebuild database, maybe malware on explorer...

So we pass... again...

Thank you dev... you have to give me back 10 minutes of my life
