bittytax throws an error if Fee asset does not match which crashes the program about bittytax

This is a current limitation of BittyTax and described in the docs.

BittyTax does not support 3rd asset fees, these are fees which are of a different asset type to those involved in the rest of the transaction.

3rd asset fees are complex as paying the fee itself becomes a disposal of a different asset in a separate pool, so needs to be calculated separately and then this cost correlated back to the original transaction.

This feature is next on the list to be implemented once tax reports in Excel format has been completed.

As a work-around for this issue, you could remove the BNB fee from the Trade, and add it below as a separate 'Spend' transaction of BNB. This will make sure everything balances correctly in the calculations, but unfortunately it won't be included within the cost of the actual trade.

Below shows how to work-a-round the fees issue, I'm currently working on a solution for this.
