Not sure if this has been reported already but i have noticed two minor bugs lately.
One of it is about the textures, particularly the rear light textures which are quite often not loaded correctly it seems. It looks like a "dull" texture that seems to be some sort of a placeholder or something. Today i have seen it happen with my own car (for the first time) and it changed while on track. I had to pit (just for repair, no shift+P/S) and the textures where normal and after leaving the pitlane again they went weird. (track was KY3R and car was XRG)
The second issue was that, after refueling once in the pitlane, at every following pitstop the game tries to refuel the same amount again although is was set to zero again (F12). It wouldn't stop until i start moving and im also getting a message saying that fuel has been added but its still the same amount. I was not able to reproduce this bug but the circumstances where as follows:
Session Mode: Practice
Fuel in tank: 40%
Fuel to add: 100%
Just in case that happens again, i will save the replay. Forgot about it this time
