There's a bug that makes clients unable to see the blue star

^As stated above, clients are unable to see the star whatsoever. Hope it gets fixed soon!

Does this just relate to the cold (blue) star, or both?
Can clients see the base and not the flame, or nothing at all?

Clients can see the base just fine, and interact with it, but the stars do not show at all. This occurs if the client builds the star, the host builds the star, the client adds fuel, anything. However, the client can still click on it and get the examine script related to their character.

Sorry, and it occurs with both stars

Also, this happens regardless of whether or not the client is subbed to your mod.

Just out of interest do the Deluxe firepit and Deluxe endothermic firepit work fine on both client and host?

Yes they do

New version has been uplaoded which should fix the bug where clients can't see the stars. Thanks for the code provided by @Kuriyukihime.
Any testers please let me know if this has fixed all the errors.

Another version has just been uploaded as one of the stars was still not showing. This version should fix all issues

i receive the error for new version, and my friends cannot join now, yet i cannot find any new version. 2.11 is the latest version i can find?

I think the sanity regen on the stars may need to be tweaked it's a bit much

dont mean to be an ass, but the radius when the star is active is huge, and it can become extremely annoying when i want to open a chest but it covered by the huge radius of the star.

The recipes aren't changing. It's stuck on the standard one. The Blue Star recipe is "2 Doodads, 30 cut stone and 1 blue gem."

I'm assuming you've opted into the caves preview Renge? There's currently a problem across all mods when servers are running the caves preview in that the server is ignoring any changes made to mod configuration. Only way around it right now is to manually edit the modinfo.lua file and change the default settings for the configuration.
