I'm organizing series at www.simracing.org.uk and I often find myself going to mod tracks for variety or tracks that are more suitable for the cars. But not all tracks are useable as some contain bugs or other issues. So I decided to gather tracks that have proven to work and make a list out of it. For the next series (Lotus 25) I'm thinking of using: Salzburgring Donnington 1938 Monaco Rouen Les Essart long Longford Thomson Road Grand Prix Circuit de Pau '67 Does anybody know if any of these tracks cause issues with online races? Thanks in advance. My list so far of tracks that have worked: Barbagello Bathurst Bridgehampton Cadwell Donnington Estoril Le Mans Misano Oulton Park Paul Ricard Riverside Road America Virginia Tracks with online issues: Poznan 1.4: Disappearing cars while they are on the curb. Laguna Seca 4.3: Car warp issues, too bumpy, sand acts like gravel Salzburgring 1.01: Walls at pit entry aren't solid and if you go through the red/white blocks, you fall through the ground.
