Scrapyards

Currently there are two scrapyards in the game: a normal one (uses Scrap) and a Scrapyard v3 (or beamyard)

Scrapyard
This Scrapyard uses Scrap as resource and makes stars cheaper at 5-9 Stars, and from x12 Stars (at 10 and x11 Stars it isn't available) evolves to Scrapyard v2, which reduces the costs of a Star (GS, Magnets and Star Fragments). Each level it gets 4 times more expensive.

Scrapyard v3
This Scrapyard is unlocked at x75 Stars (unlocked through Skill Tree) and gives +1% Magnet bonus per level, and it costs Steel Beams. The cost is equal to the level.
