It's very strange. Yesterday, i downloaded latest client + latest snapshot from official site and now i'm on wrong chain with latest block 728+

Me too. I was at block 72900 yesterday with 4 connections, so I started staking mode.
Today I wake up with 10 000 new orphans and back to block 72837 and 4 connections on this wrong fork. Now obviously I have to reload the bootstrap again.
What I don't get is there are many PoS/PoW coins out there, why did we have to reinvent the wheel with ESP, and recode something that works well elsewhere in other coins?
