I just figured my problem out.

Let's say I'm rendering to whatever acidbath.inc thingy, right? I change that to say "test.txt" and hit alt+g. It still looks like acidbath. I think the irreversability stemmed from... me not saving the file when I render. As you probably already know, any changes you make must be saved before rendering in order for them to take effect.

I feel stupid again, but at least I fixed my own problem.
