It has been noticed (not sure if this is entirely New UI or not) that some cars with custom skins (car created as a new team car) are showing up as 'Unknown' in timing screens etc. Not a big problem - but tonight, running the latest build with the official Kyalami track and GT3s (McLaren 650 in my case), I was able to practise and qualify with no problem - but between the warmup session and race, I was repeatedly booted for the 'network error' (on my side) and 'incorrect car' (paraphrasing...) server side message. I eventually managed to get in and race by loading a completely default livery... Any ideas? For what it's worth, the custom skin was not showing up properly to the other drivers during the practice and qualy sessions - I've not (knowingly) done anything different with this skin (that I created today) to any others - including the Spa 3H invitational skin our team used last week....
Just realised this has been reported by a number of people earlier. Please ignore this thread and follow the main one.
