Regarding, CSP 0.3.0 it was only released yesterday so obviously I haven't had time to check it yet. Let me know if you see other issues related to new CSP, I will try to see what I can fix in the coming days

Anyone spotted any differences between the 2 versions is there one better then the other?

My point of view is that FNR physics are more recent and so more accurate to real life, and ACU is more alive with more stuff in the environment (while FNR seems a little bit "empty")

Hey mate great work as always. Just one thing - with the new csp preview 3.0 all zandvoort extensions don't work anymore (Track display dynamic texture it says). Could you take a look at that and fix it? :) all other extensions work fine
