@ChocoMaxXx Per the FAQ's for this mod: By default, the crafting recipe for all long inserters only requires the base form inserter, and when you mine it back up, you get the base form inserter back, instead of the long inserter. You can disable this in the Mod Settings, to revert to the vanilla behavior.
If you didn't get any inserters back at all, then I might need a little more info, since as far as I can tell, Space Exploration is working as intended together.
@Twsted Hmm, I think I see the issue. By default, the new burner filter inserters follow the same logic as every other inserter I make; copy the base entity for its energy requirements, rotation speed, crafting recipe, etc. and then makes required changes (like changing the previous upgrade, next upgrade, etc). In vanilla, the stack and filter inserters use the basic green circuits and gear wheels, just a lot of them, so it's not actually gated behind any other tech. But of course, this approach won't work with more complex mods.
I suppose the simplest method of handling this would be to change the ingredient requirements to copy the basic burner inserter instead, and then maybe doubling or tripling the ingredient amount, to balance the cost a little bit. I probably should have been doing that before; it makes a bit more sense to me that way.
