I 've a two node setup with every default configuration. My node1 holds all the wallet addresses (created using getnewaddress) 
When I 'm trying to transfer an asset from admin to another wallet using the CLI, the transaction goes through. Now when I repeat the transaction, nothing happens. I change the amount, the transaction goes through and then when I repeat that amount again, nothing happens. Is it a issue or limitation with the blockchain itself or it's a CLI issue? When I see getaddresstransaction for the transactions where assets were not transferred I don't see anything inside the asset block. This behavior is really weird. Does it have something to do with unspent transactions? Anything else which I can check to understand the issue.
