CG pls fix your shop

Losing crystals due to shop lag is unacceptable. I was buying upgrade materials from the supply drop, and because of the lag, the 1280cc shard pack that was underneath opened. It happens almost constantly, and the first time I wasn't 100% focused, I threw 1200cc at a character who already had 7 stars. Please fix this annoying lag... the game has been stuttering ever since you threw away that Colosseum mess.
