according to the engine api Animator | LoadAnimation creator docs no it is not deprecated.
It is for the humanoid but not for the animator
I did that, still no change, anything else i can try?
also heres the character.
You can try the Animator:LoadAnimation() method, it always worked for me
ONLY if you’re using LocalScript ( referring to Animator:LoadAnimation() )
Hmmmm, is it after you clone the character?
I animated a box once and it worked fine on a server script
ServerScript or LocalScript, both will work since the Animator:LoadAnimation() has the same result as using Humanoid:LoadAnimation()
yes it is after the character is cloned.
No, Humanoid:LoadAnimation() is deprecated
Another thing you can try is make the “Animate” inside of the character
I already tried that, still no results.
Can you show me the inside of the “Animate” ( Not the code ).
here it is.
if found out animate uses humanoid:LoadAnimation()
IT HAS NOTHING TO DO WITH THE GLITCH BECAUSE WHEN I DISABLE THE CHR SCRIPT ANIMATE WORKS
Basically, you need to change it to ServerScript to make the animation work or you can change it to
currentAnimTrack = humanoid.Animator:LoadAnimatiom(anim) -- Use this one if you're lazy to just change it to ServerScript
it has nothing to do with the glitch 
Can you explain what you meant by this?
What i mean is when i disable the script which changes the plr’s character everything worked fine.
One final guess from me is the character’s HumanoidRootPart is anchored
it is not as i am able to move. Script just be broken ig.
