WP Returned Unnecessarily

[Curiose]

Originally, I had only 1 wishpoint from the days achievement, however. Once the WP refund happened, I found that I had an extra wishpoint. I should NOT have an extra wishpoint because I used the one refunded on mirrorritual. My first wishpoint that I received was used on Locate.

I now have 2 wishpoints.
I have also checked my spells page, and I still have mirrorrit.
