im wondering if you can help me im in the yellow server and my snorlax got beat by lances dragonite but in effect was stealth rock and i sent out charizard at half health and it knocked it out instantly and it also killed butterfree also at half health now i know rock are super effective to flying types like char and butter but surely from two half health pokemon even char who had leftovers should have survived or even held on if you can check to see if this is a bug i would really appreciate it cause i spent alot of time training and gathering resources and dont want to rage badly cause of a slight infraction yours sincerely Therichricky

Because your pokemons' fire type and bug type in addition to their flying type, they will take x4 damage from rock. Normal is 12.5% max hp damage taken from stealth rock so with x4 weakness they will take 50% of their max hp. From your example it seems like it's working as intended.
