also since i have so much of everything, i can spam upgrades which SEVERELY lags the game
EDIT: i have no more beautiful gold pile :(
Yeah in the late game spamming upgrades as well as just opening the prestige/artifact panels can lag as they aren't very optimized yet.
Gold number truncation is also coming.
And I feel you on the gold pile. It pains me that in the late game you can reach states where there is no more beautiful massive gem pile.
