When loading this mod along with F3, I get this error.

Failed to load mods: Error while loading sprite prototype "visible-planets-nauvis-factory-floor" (sprite): Key "filename" not found in property tree at ROOT.sprite.visible-planets-nauvis-factory-floor
Modifications: Visible Planets in Space

Disabling either one of the 2 mods gets me past this point. I'll report to Factorissimo 3 dev as well since I'm not sure the root cause.

The author of Factorissimo 3 shared this:

"Thanks for the report. It seems the other mod does not properly handle the case of missing starmap icon for a spacelocation. For this reason I will mark this ticket as closed. Hopefully visible planets in space pushes an update to resolve this."

This seems to be an issue because Factorissimo adds "planets" for each surface's factory floor, probably so it can show in the remote view select menu.

I'm looking into it now. Factorissimo can technically fix it on their end by blacklisting any new planets they make, but ideally I can just detect that a planet will have this issue and skip it on my end automatically.

Ah, you posted as I was typing. Yea I'm on it :)

Latest version fixes the issue. Factorissimo was defining a starmap icon size for each location, despite not having a starmap icon. I don't actually remember why I was checking the icon size and not just the existence of the icon, so I've just changed that to fix the issue.

Thanks!

Sweet - thank you for jumping on it so quickly!
