I didn’t have a chance to test all of her skins but at least for Persimmon and Mei-rry, the secondary fire on her Endothermic Blaster produced a red icicle instead of a blue one. Her Jiangshi and Ecopoint: Antarctica skins shot the usual blue icicles, so I think the bug is related to specific skins.
^This. I have tested the other skins as well. Video: https://youtu.be/b49ms7Z0FMs
This bug happens for these skins:
Skins not tested: Pumpkin, league skins other than London Spitfire
Mei bug: visual secondary fire shows red icicle (right click) for certain skins
Bumping because this needs more attention. I’m also having this issue, even after the 1.31 patch.
I have also noticed this visual bug on the Mei-rry skin, specifically when using the golden weapon.
I also notice a bug that when freezing a junker skin dva mech, there is no visual effect, so it is a bit hard to tell if dva is frozen or not.
