There seems to be a big seam in Silverstone's Abbey corner geometry that makes the FISI 2012 bottom out. It is somewhat similar to the issues with some track surfaces that appeared with the DX11 update. This big bump in Abbey is annoying because then you can only take the second part of the corner with DRS opened.
@Alejandro1 There was historically a huge bump at Abbey entry in real life, so I don't think it's a bug. Not sure if it has been improved in past few years, but the one that rF2 scanned is based on 2012 or 2013 version. "The new part of the circuit is certainly interesting. It's very fluid and fast but there is no overtaking possibility which is a bit of pity for me. The bump at Abbey is tricky, a lot of the drivers had to really work their steering wheel, so it is likely that this will be discussed more deeply in the drivers briefing today."
