Not sure whether this came with the 2.02 update or spec 2...
I go to practice a track (as per this weeks WRS time trial) run a lap, save the ghost/best lap replay and then exit to replay theater to check it over.
If I then go back to the same track in the same car, it won't let me load up that ghost replay immediately. I have to go to track, run the car for a few seconds, and then exit out to load up the ghost replay.
This certainly wasn't the case before 2.00 but I haven't played much between then and now to know when the bug was introduced.
Disclaimer: have only discovered this on Tokyo R246 reverse so far, but have not checked any other tracks
