BUG: Interaction with transformed Smeargle lost title (but not damage) of known move for Flygon

[jmynes]

After transforming into enemy Flygon, they later switched out, and then back in.
After switching in, the 1st move slot switched to ---, but kept the damage calculation of Rock Slide

In a follow up match that I don't have the replay link for, I had a damage roll for Earthquake as transformed Flygon vs Flygon, despite immunity.

In another follow up match I seem to reliably be creating the conditions for earthquake to calc against immune opponents, after switching off Transformed Smeargle

[jmynes]

I think what it's doing is blanking any move of the opponent's set that I didn't use while Transformed?
It seems to be a reliably replicable bug

[jmynes]

I see now why it's unsetting the earthquake immunity on Gengar, the enemy ability is accidentally getting set to Own Tempo
