Regretabely this mod doesn't currently work with other modded Silos
In case of Heavy Cargo Rocket Silo it spawns another silo on top of it.
And in case of Big Rocket Silo from Paracelsin and Advanced Rocket Silo from Linox it replaces them.

That's true, it wasn't really made with modded silos in mind. I'll see what I can do. Maybe at least a safety check for specific modifications.

I adapted the mod for Larger Cargo Rockets specifically and set ignore for others for now. Do other mods allow their silos to be built on different planets or are they typically locked to their home world? I haven't played a lot with modded planets myself.

I don't know if it would interact with other mods in this way to begin with, but, would this mod be compatible with Muluna? Afaik it doubles resource cost for rocket parts, don't know if that could mess with this mod :c

Thank you Maxorio! :D

I added a theoretically universal modded silo support (with settings) but if anything breaks please open a new report here.

the mod doesn't load with rubia:
Error while running setup for entity prototype "rubia-rocket-silo" (rocket-silo): fixed_recipe="rocket-part-rubia" cannot be used on this machine. Reason=DifferentCategory

I suspected the recent change might break things... Try loading the previous mod version and see if that works. I will look into it later.
Yeah, the problem can be the RocketCargoInsertion mod requirement specifically. I'll look into compatibility.
