Orphans are coins you never received - this happens in all POS altcoins.
Orphans or Conflicted transactions are ones you never actually received.
An orphan occurs when you and another wallet POS at the same time and,
the POS is awarded to one of the wallets. The person not receiving the POS retains
the age of the block to compete for another POS reward. The wallet receiving the POS
has the age re-set to 0.
Orphans may also occur due to a slow connection.
Here is one of mine from XDE2
In many coins, these conflicts can be removed from the transaction display by using repairwallet.
It really just takes them away since they are not in the blockchain. Aesthetics really so you don't have
to continue looking at them.
Also, sometimes it appears you receive coins but, you get off on your own fork which could
possibly happen when a wallet version changes. To check on missing coins, copy the transaction
ID and paste it into the Block Explorer. If it exists then, you can recover the coins by
going to tools - wallet repair. My personal choice when I have problems is repair wallet and if that does not work,
recover transaction 2 (zapwallettxes=1). 1st you need to be sure the coins were actually awarded so start with the block explorer.
