Nah you're good but yeah, I agree with that—it's an absolute waste of time given how flawless the current version already is. Anyway, I’m not sure how your levels could have gotten corrupted. I mean, if you play them through "Terror Engine" they might look "corrupt," but if you play them with the Sad Satan standalone .exe, the levels should look correctly. You can always start playing from the level you want if you rename it "1" (both .story and .level files). The standalone.exe always starts from the level named "1".
