Known bug, the solution for now is NOT to change your characters size when first created. Any size other than the default will cause the physics NOT to work eventually. Just leave the character created the size that it was defaulted to upon new game. You can change all other appearances bt NOT the size / height of your character. Reported elsewhere as “Armor Physics Broken” or something like that.
Thank you for the info, but being already at level 50, I do not see myself starting the game again …
But this trick will serve me for another game in the future.
Anyway thank you very much.
