[GAMEPLAY] Jade Fang Cassiopea's W is invisible to enemies

I just got out of a game against Jade Fang Cassiopea and nobody on my team could see her W on the ground. She said she could see it, so there's that.

How to replicate it:

1. Have Jade Fang Cassiopea on the enemy team.
2. Have her use her W.
3. ???
4. Profit

I would've taken a screenshot but y'know it'd be of nothing. I have the replay.gg file available if that helps.
