Hi there!
There's a bug involving speed on RBY, where slow/para mons are being able to outspeed mons that have higher speed.
I play RBY a lot and this has been happening quite frequently, where mons like Snorlax or even a para Starmie are able to outspeed healthy ones like Chansey or Jolteon.
This is happened in my latest match:
The last 3 turns were a example of that
Turn 41: Starmie is fast asleep appears/happens BEFORE Jolteon's Thunderbolt, even though the latter is faster
Turn 42: Snorlax is able to Rest before Jolteon's attack????? Snorlax is the slowest mon in RBY OU ( with Slowbro), how is it possible for him to attack before Jolteon?
Turn 43: Snorlax is fast asleep appears/happens BEFORE Jolteon's Thunderbolt again (just like Starmie).
As far as I know, this is not suppose to happen

BUG STATUS: NOT A BUG In RBY, the paralysis Speed drop doesn't reset after using Rest. Your Jolteon was slower than the other Pokemon because of that speed drop (Irpachuza).
