I'm looking through it myself now and I'm not seeing it either. The copy I have on Github doesn't look like it has any incidents of ints instead of floats either. I assume you're working with the current version since I know you tried the new SimulatedLighting, so I'm not really sure where this is coming from. Can you throw your MVNRSP file to me in Discord at some point?
