Yeah I find it highly unlikely this sort of thing would be a software glitch. Someone made either a mistake or deliberately told their 3D modeling artists to make the players look stupid (same thing happened in 2006).
The only possible way it’s related to a bug is if there is a collision problem and they had to adjust the models for it, or they actually have an algorithm that designs the models for them (but even that’s less of a bug and more of a failure of algorithm design).
