Ahh, I know the issue; it's actually an RSCompat problem.
I had some very specific compatibility code that ran when Moshine, Linox, and Cosmic Social Distancing were enabled, moving Moshine away from Linox/Vulcanus (to prevent CSD from pushing Linox any further towards the sun).
This mod properly sets the CSD exclusion, so it isn't being affected by CSD in this case (which means it won't affect Linox's position anymore) so just needed to be fixed in RSCompat
