Send yourself 5000 coins again. Try again. It's obvious you didn't send exactly 5000 coins.
I cannot send myself 5000 coins again as it states that I have insufficient funds even though the 5000 show as available on my dashboard. In my coin control is shows my original amnt over 5000 as (change) and shows 2 masternode payouts but the 5000 actually in the masternode doesn't show up.
In transactions the payment to myself (masternode) is shown as the -0.0001 SYNX fee.
So if my vin cannot be allocated yet the masternode is somehow still paying out what is going on?
Maybe you are just staking your coins instead of masternode.
For me when I have my coins in masternode I can still send coins to whatever wallet. It's not locked where I can't send.
If you don't have masternode output that means your coins can't be in masternode.
