the fork point (last block identical in both chains) is 5938411, time Aug 13, 2018 23:08:20 GMT
for those who want to jump on cryptopia chain:
close wallet, backup your chain and your conf file,
roll back your chain to any state before the fork time (use any snapshot you're confident in),
restrict your connections in conf this way (only temporary!):
connect=23.233.2.252
listen=0
sync up, restore conf file, restart
P.S. i hate checkpoint servers
