Switching Autoconvert coin resets earnings history

[nowwhatnapster]

I switch my autoconvert coin on MPH from Bitcoin Cash to Dash. I went to MPHS and updated my autoconvert coin to match.

This cleared the history of earnings on MPHS.

I only had a few days of history so not a huge loss, but I will be changing my autoconvert coin again in the near future. It would be great if the earnings history didn't get wiped out.
