Delta Noibat and Roost

[Former user]

While training the delta noibat,i obtained in the mysterious hideout, I noticed that when I used roost, a stunky's slash and feint did normal effectiveness damage. It also proceeded to poison me with toxic. Delta Noibat is a steel type pokemon and can't be poisoned, nor hit normally by those other moves. I think the bug here is that instead of removing immunities caused by the Flying type (as it should), it removes /all/ immunities or something along the lines of it. I hope this is fixed soon~
