I'm using alpha-28, but have also tried updating to beta-1, which doesn't resolve the issue.
I'm spinning up 2 instances of multichain, one connecting to the other. I create a stream in the master and subscribe to it in both nodes. I have also configured the chain to allow anyone to connect, create, mine, and send. When publishing to the stream from the master node, it works as expected, but when attempting to publish from the second node, I get the following error:
No unspent outputs are available. Please send a transaction, with zero amount, to this node or address first and wait for its confirmation.
I'm not sure why this only occurs on the "slave" node and not the "master". I saw a forum question which seemed to be vaguely related, and the recommendation was to upgrade to alpha-29 or newer. I've tried with beta-1, but there's no difference in result.
Am I missing something obvious?
