i use my computer with system windows 8.1, setup the 0.2.0a wallet
when i syncing the blockchain.
the height increase to 256670/259356 and then the height became decrease.
is this a bug ?
because i just setup the wallet in a normal way in a normal computer with windows.
or just the wallet is no stable in windows?
This is normal behaviour, as a fork countermeasure. Just wait and let it sync until end. If this still occurs, then please send the log files to us. (bugs @ crypti.me)
