Update: I’ve added debug box (the current linear velocity should not be able to escape said box), yet is does just that with ease. I’ve tried to use AddForce instead of changing the velocity directly, I’ve tried to add two forces separately for each axis, I’ve rewired the control logic so that I can be sure of the order of it happening, yet the problem still persists.
You can see how the velocity, that should just be reduced leaves its possibility space:
What am I doing wrong? I don’t get it. At all
