Simple Shops 1.2.2 causes Apotheosis-1.20.1-1.1.0 gems placed in shop to not check for gem rarity. This allows you to be able to pay with any gem rarity as long as it is the same gem type. When you draw the profits from the shop, the gem of a different rarity that was used to purchase an item somehow becomes the same rarity as the initial gem that was used for the price section of the shop.

For example...

• Put a flawless ballast gem in the shop's price area,
• Pay with a cracked ballast gem
• withdraw the profit and initial gem placed
• have 2 flawless ballast gems

I hope this made sense. I'll provide any more information if needed
