Tryed to simulate it a couple times and if you change from settings to upgrades you get the settings bar length, same with managers when you change from managers to upgrades you get managers scroll bar length
The game is awesome but sometimes when your going to scroll down the upgrade menu, you get a bar that is too big and when you only move the bar down a little it umps to the bottom and the bar turns to a normal, shorter state. Just a minor glitch nothing major.
