Instant invincibility gets an extra round if it’s hit by rampage/impact and run. What’s up with that?
I’ve both won on a “sure loss” and lost on a “sure win” by this bug.
In worst/best case (depending on your side) the instant invincibility will stop 3 hits, the hit & run, the swap in ability strike, and the following hit next round.
Hey Nostrada, I’m sorry that happened in your battle. Our team is aware of this issue, and they’re currently working on a fix for it.
It’s OK.
But i think it’s important that everyone knows of it, so they can play on even terms. 
Instant Invincibility will stop Damage and Run move and SIA if it’s not Shield Breaking or Nullify. Stopping the following hit is a bug.
Correct me if I’m wrong but im almost 100% certain that Ludia said a few months back that thats the way it was suppose to work. Their words i believe were “it was always intended to do this”. Even when a bunch of people brought it up they defended it as a mechanic that was meant to work that way even though it made no sense.
