We got another small patch for you, fixing some of the remaining issues. As far as we know, this puts the game into a solid state again (well... apart from what is noted below) and we can continue with improving more aspects and tweaking.
Note: We're currently investigating why on specific Mac hardware, starting any race results in a game crash. Due to this happening on a game engine level, it is very tricky to work out what is causing this. We will be flying blind in fixing this as there is direct way to debug it. We have contact with some individuals who get this type of crash and will be iterating to figure out what in the rendering pipeline causes this malfunction.
Cheers!
