I just started staking some NAV a couple of days ago.
out of 4 possible 'stakes' 2 of the 4 are orphaned, or as the transaction says:
Status: 0/unconfirmed, not in memory pool, abandoned
Date: 10/13/2017 12:05
From: unknown
To: NXstuffaddy (own address, label: mylable)
Credit: 0.08767123 NAV
Net amount: +0.08767123 NAV
Transaction ID: 79ed4af97284ca4a604415027c47b636337e5417ec499a3cf5aeaee319d36487
Output index: 0
Is this normal to have 50% not work?
