Coin Spent links to the wrong transaction

it has 3 outputs, where the first two have the same balance. clicking the red arrow on any of them links to the same transaction, even though output-2 is spent in a different transaction, here:

Yes, unfortunately Blockbook is getting the spent links only heuristically and this can happen.

This is still occurring, surely this can be fixed if you are currently able to mark the outpoint arrows as red correctly.

Additionally the spentTxId information when using the spending flag on the tx api is wrong.
