robots.txt, .htaccess redirects not updating properly

I’ve noticed a few bugs on a few files on a site I am helping a friend with that are not updating properly.

1) when I update my robots.txt file, the changes do not take place;

2) I made a redirect in my .htaccess to direct non-www to www version, however when I comment out these lines of code the redirect still works;

3) A couple weeks ago I put in a redirect on my .htaccess to direct mobile users to my m.domain site, which worked, however now when my JS files have the ? query string removed, these files get redirected to the exact same file path except now on the mobile version. For example, example.js?ver=4.2 works fine, but example.js will redirect to m.filepath/example.js.

I’m stumped as to why this could be happening. This is all taking place without any cache program, and on multiple browsers. It’s like there’s some kind of phantom code monster hidden in my back end sent to piss me off :<

Here’s my .htaccess if that helps:
