Context (please provide as much as you can)

Apparently the variable loadingscreen.timeBegin is not available, missing initializer? Not sure if there would be any sideeffects by just making a convar check in loadingscreen.end as well or just initializing it. But the code in .end should not be run, if the loading screen was never shown. Otherwise if the screen was shown, that should be called to reset some variables, even if the convar was changed at some point.
