Trading with unissued assets

Help needed to interpret exchange transactions with assets which never issued. Example: https://testnet.wavesexplorer.com/tx/D9kvwJy5FeGNkFPi6Ap689CiybPPEHr2UmDA53zhYumY

This tx looks criminal but it is on the blockchain.

How it is become a legal one? And how to interpert it on a balance calculation?

@deemru
thank you for your attention, we are going to investigate that situation.

Will keep you updated.

Any news? I need to continue parsing the TESTNET.

Hi @deemru,
@peterz did the fix https://github.com/wavesplatform/Waves/pull/1363/files, the patch is already available on TESTNET.

Ok, TESTNET was reverted back, there is no problematic txs anymore, thanks.
