Same, hope this is fixed!

What exactly do you mean by "damaged first person view"? Do you maybe have a screenshot for me?
The visual bugs seem very strange to me, since we run the shield (as the same addon as you) on our server and don't have bugs like this. I'd be happy if you could provide some screenshots of that, too.

Also, the traitors starting with a shield is fixed. Sorry about that.

@ screens: i threw the shield, picked it up and threw it again

(On my server, I have fists as additional melee-weapon)
the bug also occurs for spectators in 1st-person-view on the detective
(again fists and magneto stick ... other weapons I've seen so far, I haven't seen any problems)



// Edit -- additional bug + screen:
you can deal Damage to spectators / dead players, when running (right-click) with the riot-shield

Thank you for your plentiful investigation! I had the fists addon myself but threw it out because it was buggy. I will look into this and see what I can do. It seem that you're having trouble with resetting the bonemods I used to make the riotshield appear in your hand.
