Yeah, that's a known visual bug. When you go from X days to X-1 days 23 hours, it keeps showing X hours for a while. If you check back in a few hours, it will have corrected itself.
I have never known a game with so many glaring bugs in it.
I set up an upgrade 2 days ago which takes 5 days to do. 2 days later it still show 4 days and 23 hours plus a few minutes.
How can anyone take this game seriously. I have had drivers in the past who did the practice but never appeared in the qualifying or race. I have had setups changed for no apparent reason, just to name a few.#
If the bugs were ironed out it would be a decent game, but it looks like no one is bothered about sorting them out.
