So me and my friend were playing around with our Tapus until one battle I used Tapu Fini and we noticed that when I used Scald it burnt the pokemon and we weren't sure of this so we decided to test this again by finding a pokemon that is touching the ground and battled it and used a status effect move and it worked. We tested it on a wooper used misty terrain and then I used my Gliscor's toxic and it actually worked instead of preventing it, it went through. So we figured to report it since it was clearly a bug.

Thanks for the report. This is a duplicate of https://www.pixelmonmod.com/tracker.php?p=2&t=13109 , which seems to have flown under the radar (which is kind of sad considering the comments on there... oops!). I'll bump it up on internal. Keep an eye on that ticket to see what's up.
