Your Gun Sites

Since the 9.4 update I have not been able to get your Gun Sites to work.

Can you tell me which file control the sites?

I have in the past been able to figure it out but seems like since 9.4 things have changed in the game to not make them work.

Also since 9.4 I have not been able to fix my carousel for multi line? To your knowledge has something in game changed this too?

Thanks I know you are busy but after trying all day I am at a loss.
