This will certainly fix a lot of things.

I didn't even know that existed; can you tell me what that function does?

@sfan5 With all due respect, this pull request has been open since before I finished middle school. It has received a few reviews from you and corpserot, but no talk...

Ok, I'll try to separate it into multiple PRs.
