Thanks for all of the feedback everyone!
Trees - We're working on improving the positioning of these, so they don't overlap water, road,s buildings, etc
Airport Elevations, Floating Taxiways, etc - Very much a work in progress
Rainbow Terrain Chunks - We're still working on this, we've seen it a couple of times in-house. The issue is it takes so long to reproduce, and is rather intermittent, so we're having trouble recreating it enough to determine the cause.
velador73 - Thank you so much for the great reviews
