Client Duplicate mini-sprites if a repeated species is revealed after a faint

[apo99]

What type of bug are you reporting? Random Battles

What is the bug?
I had a whishcash aint due to toxic and then come back at full health like it was switched in (got badly poisoned by the 2 active layers of toxic spikes). Won the battle with 1 pokeball remaining in their queue.

Are you able to replicate it? If so, how?
No clue, hard since its random

Could this be because of a zoroark? The first Whiscash was never hit by an attack so I don't think it would reveal.

I didn't even noticed it... it was an Illusion.
But the client should at least be able to know that the first Whiscash already fainted and display the second Whiscash on a different mini-sprite.
