A few times i tried:
Delete all files except wallet.dat and resync, takes 3 days to sync but somehow get on a different chain again. Everything looks reasonably normal, i have 16 connections in and out and there are 32 masternods (28 OBF compatible and 28 enabled). The only hint that i have that im on the wrong chain is that im getting too many stakes, after checking on the official explorer i see that 'my' chain has a different block height.
According to the official explorer my last stake was on july 8th.
Any idea how to solve this? Strting from scratch doesnt work since i tried 3 times already.
p.s. running wallet 1.6.5.1-23453b7-dirty
try using this blockchain and make sure your transaction in official explorer
