m&m_day.mip appears to be missing. It's used on a hauler in the infield. I have a feeling it got excessed by mistake by NR2003Datter. That happens to me a fair bit.
A little odd to see a track like this with only a fence on the outside, but I'm going to guess that the track you were modelling off of was also like that. The other thing that stood out is that highrise office buildings lit up like that in the daytime.
Other then that, the AI looks a tiny bit questionable, particularly on pit exit and down that straight. For tracks I've put out, I've often re-done LPs numerous times during development. Thankfully those aren't that time consuming to do.
It's a bit refreshing to see a track without billboards on it, and the progressive-ish banking is neat to see.
Got a bit of work to do on the details, but what's here right now is pretty solid.
