After downloading Maraxis and placing down a new rocket silo on Aquilo, I noticed that it defaults to the vanilla rocket part recipe and cannot be changed (since Maraxis adds a new recipe for rockets specific to the ocean planet). I'm not sure how easy it would be to implement as a compatibility, but having such compatibility with planet mods that add planet-specific and/or alternate rocket part recipes would be nice

+1 on this i was looking at how to change recipes but found no way to do it

I already made a post on how to get around the restriction, link is here: https://mods.factorio.com/mod/space_age_galore/discussion/68228eb33d149105f322c34c
