I play with Bitcoin Core 0.13 in regtest mode using python. Now I use bitcoin-testnet-box, I have two nodes connected to each other. I want to create a walletconflict. I want to get gettransaction <txid> result with non-empty walletconflicts field.

How can I achiev this?

I've tried to get two different addresses from one node and send money to them from another, using raw transactions api and -zapwallettxes restart, but the second txid is not visible in the recipient wallet.
