So I do not have a screenshot that can demonstrate this bug. You only have my word as a player that something happened here, and maybe you ca duplicate this bug.
I completed Accursed Experiments this morning, and the full prize basket was given to me. Last night I was selling extra Filia moves...
THIS IS FOR GOLD TIER MOVES ONLY
For those wondering how much it costs to upgrade a skill from 1 to 15, here is some info. Anything not shown in the picture is because I don't have the info myself yet.
For those just wanting to know the total cost from 1 to 15, it's 2,935,000 canopy coins...
