Male Viera's feet animation while running/sprinting

Date & Time: December 11th, 2021
Frequency: Constantly
World name: Faerie
Character name: Psycho Mantis
Steps:
1. Run/sprint forward
2. Set camera behind the character while running
3. Look at legs/feet, especially the right one
4. Notice it doing a weird movement


I have talked to more people and they also noticed the same issue. Sadly, I can't record a video in slow-motion to show it, but it shouldn't be hard to spot anyway.
It happens especially with the right leg/foot, and it looks like the character has a broken foot/ankle, so it just does a very weird floppy movement. It is also more noticeable when sprinting, but it can look weird while simply running, depending on what shoes you're wearing.
