Quote from Flame CZE :

I'm currently having an odd problem in H5. Whenever I go to the pits (Shift + P), there is a 1 to 3 second delay before it shows the garage GUI. It just shows the garage background during the delay.

I tested it with a clean LFS install and it occurs in H5 only, it's fine up to H4.

Anyone else with the same problem by any chance?

I have the same problem.
Some times i have this message "LOCAL: TIMER BOUNDED"
I am running 0.6H5, single player, no AI, Windows 10.

Delete the contents of the Temporary Internet Files folder if you have problems with corrupt file.
