There was big update in Angels mods: https://github.com/Arch666Angel/mods/pull/659
TLDR: cobalt and gold was moved to "crystals" tier. Silver was moved to "chunks" tier.
Now there is a problem with "Intermediate Structure components":
it requires cobalt plate, but cobalt ore can be produced from "jivolite crystals refining", but those crystals require "leaching plant 1" and that building requires "Intermediate Structure components"
I would propose to:
1. switch "cobalt plate" to "aluminium plate" in recipe for "Intermediate Structure components". Because aluminium is produced at "chunks" level.
2. switch "aluminium plate" to "cobalt plate" in recipe for "Advanced Structure components". Also it could be for example "gold plate" - because there is already "cobalt steel plate" there, so maybe "cobalt plate" would be too "duplicatish". Or maybe just remove "aluminium plate" from this recipe (because it will be already in "Intermediate Structure components").
@Archemide what do you think?
