After doing somethings with Cyberware my hand moved to the left side. I knew what caused this, the right cyber arm. BUT after I removed the cyber arm wanting my right arm back, it stayed on the left side. Later I made a new world to test some thing and my hand was still on the left side.

Also if I try to change my main hand in Skin customization in the options it flips to the right for half a second than back to the left hand

was this ever fixed?

Try changing it in the customization options on the main menu instead of ingame

Tried that. Still flied to the left side

I have the same problem.
It just swaps it back to left every time I change it in the settings menu.

i have the same issue in 2020 i become left handed after relog on interaction pack
