It happens to me sometimes do you have many nodes on your folders on my first three days of staking my wallet I also had a lot of unconfirmed transactions but now I rarely got them I also want to know this issue I am also experiencing these on some of the coins i am staking i don't know if it because I am mining to many coins or what..
I copied my appdata somewhere else and saved it safely in another file -my appdata contains my wallet.dat and other files.
Next, I deleted my appdata from roaming.
I then synced a fresh wallet from start. After sync, I replaced my wallet.dat in the new appdata file created in roaming.
issues were resolved when I opened my qt-client
i got it 2 sometimes (still) , i thought i was agains the bigguys ( wallet wits huge amounts) because we found at the same time sameblock and bigguys gonna be first , this is my guess , i dont know
@BitTyro : how many BIGUPs do you have ?
BTW for staking , the wallet doesnt be active
