Broken Buyscreen Bug
A weird bug that only happens to small number of players is the bottom half of the buyscreen missing or being inaccessible.
It's not the same bug that messes up some buyscreen buttons caused by ALT+Tabbing/minimizing the game many times.
You can fix it by setting your Windows DPI settings to 100%. (In the windows Display settings)
An alternative way is to edit TacticalOps.ini manually with notepad, in section [TOSystem.TO_RootWindow] and edit as below:
[TOSystem.TO_RootWindow] bTORetail=True GUIScale=0.800000 LookAndFeelClass=UMenu.UMenuMetalLookAndFeel ConfiguredGUIScale=1.000000 AutoGUIScale=False
A third (untested) way is to use these 2 console commands:
set TOSystem.TO_RootWindow GUIScale 0.800000 set TOSystem.TO_RootWindow ConfiguredGUIScale 1.000000
