Hello,
This mod only affects the first/primary surface in a game. This is by design - as there's no way for me to tell what another mod's intent is when it's adding other surfaces. (eg if it's a factory building that should always be dark, or something in space that has special properties, etc).
If you're using a mod that fundamentally changes the primary surface... well, that's also something that my mod can't really determine through code. For such a mod, it is probably best to turn off Clockwork and let it handle its day/night stuff internally.
