Custom playermodel arms are twisted and offset

[SDWAN]

I've been dealing with this issue for the past 2 days and im starting to get severely annoyed by this. I've used the proportion trick so I could keep Joker's posture and body length. EVERYTHING WORKS except the arms. I have a feeling it's due to IK chains and what not, but im not sure, and I am very vested in finding a damn solution right about now.

I tried adjusting the reference to see if that would fix anything

It barely did much and im starting to get tired of this heavilly. Here are some other pictures

PLEASE. I am getting very annoyed by this problem as i've been getting this same issue for other custom playermodels

[SDWAN]

Can I at least get some type of response to this?

[ficool2]

Ikchains aren't compatible with the proportions trick, so remove anything related to IK or spend 3 days trying to fix it
