Big numbers no longer break. Past nine quintillion the counters used to roll over into a negative, and the exchange sign showed a twenty digit minus across the screen. The whole economy was rebuilt on a number type that reaches far past anything a farm can produce.

Number suffixes go past Qa. A leaderboard reading "4210.26Qa" now reads "4.21Qi", and the ladder continues for another forty ranks after that.

Counters no longer show four digits before the suffix. A balance printed as "1000Sx" now reads "1Sp", which is the same number written the way it was meant to be.

Exchange upgrades stopped being free. Past level 500 both the price and the bonus were frozen, so every further level cost the same and gave the same. The cap is gone and the price now grows with the level.

The leaderboard no longer flattens everyone at the top into the same number.

Farms already broken by the overflow are repaired on load instead of being written off.

Closed a hole that let a modified client hand itself coins, cards, spins and rebirths. The commands behind those were already blocked, but the requests underneath them were not.
