Anything with intercept in is a complete non-starter. You still fully
duplicate the logic.

You really didn't get anything I said, did you?

Please as to go back to square 1 and read again.

So take a step back and try and explain what and why you're doing
things, also try and look at what other people are doing. If I see
another patch from you within two weeks I'll simply delete it, there's
no way you can read up and fix everything in such a short time.
