Upon further inspection of your files, it does seem very likely that you have a mod that changed AI spawns and behaviour but it isn't showing up in the logs (not from what I can tell anyway).
As for the sights and scopes issue I would need you to do what I advised in the screenshots and report back to me for further assistance.
Just so you are aware, if this thread has no response for 3 days I will have to close it and you will have to make a new thread.
