I quite appreciate the optional setting to have the Stirling Generator require Lithium so it doesn't impact other planets' progression. Would it be possible to also have that setting hide the unlock of Stirling Generator behind the Lithium Tech so it doesn't show up in the crafting menu until you have access to Lithium? I like having this mod in even when I'm not starting on Aquilo, but it makes it weird having that in the crafting menu when it can't be used yet.

Thanks!

Should probably be possible; not sure when I'll have time to get around to it, but it's a reasonable suggestion.
