I managed to find the issue in the form of belt recipes conflicting with bob's logistics' own recipes and the functions his specific mods use to change existing item recipes. But uninstalling that led to another issue involving Realistic Fusion Power which I couldn't get a lead on.
That being said, I don't think that save file is a good fit for this mod since I didn't plan on it being used alongside major modpacks. That's because of both the content being redundant and because of potential incompatibilities like this that would require a bunch of time writing compatibility patches for. This is more of a reimagining of the vanilla game than something to add a ton of content.
