I got sick of starting a championship game only to have is spoilt by the pit lane entry bug so I tested every track I own so I know which ones to avoid when setting up a custom championship. Note that it doesn't matter what class of car I use the result is the same so it is definitely track specific. Each track that had a bug I tested 3 times and each time the bug occurred...so it's consistent and 100% reproducible (well on my computer anyway). I also ensure I din't exceed any track limits before entering the pits. The Exceeding track limit warning bug doesn't cause a penalty but I'm not sure how many warnings you get before it does. The following tracks have this bug Bathurst Hockenheimring Hungaroring Moscow Raceway Slovakia Ring Some tracks immediately give you a Drive-through Penalty bug (dependant on your settings of course) If you have your settings set for "Slow Down" then it just slows you down a bit so they are playable but is frustrating as that extra 1-2 seconds can cost you a lot of places. These are tracks that have this bug Redbull Ring Speilberg MotoSports Arena Oschersleben Spa The following tracks I have not Tested as I don't own them Chang International Circuit Macau Paul Ricard Salzburgring Shanghai Suzuka How the devs fix these soon and until then at least we know which tracks to avoid.
Will apparently be fixed soon - https://forum.sector3studios.com/index.php?threads/pit-lane-glitch-hockenheimring.5004/#post-67916
