Qin Long's limbs getting stuck and bending when going up steeper slopes or resting on steeper slopes

When I play as Qinlong and do precise movements up and down slopes, I notice that Qinlong's front limbs have some stuttering and bending issues.

I thought I must have seen it wrong, so I tried it again. When Qin Long uses precise movement to move diagonally on steeper slopes, its limbs really do bend incorrectly. Also, when it rests lying down on a steep slope and then gets up, its limbs bend incorrectly again when standing up.

Using precise movements to go diagonally up and down on steeper slopes and getting up on all fours on steep slopes without bending the limbs should be a normal posture.
