I had read someone else had crashing with Neva, so I hadn't even installed it while using this build. Just loaded it up and it ran fine. Question: Is it possible that you updated (not fresh install) and didn't delete the cbash files before running it again in the 798 build? My 798 is fresh and I cleared all files except packages. While running on the track it is easy to tell gmt's and such are different with this build because track (while dry) is extremely shiny in places as if it had just rained. (I think the Indianapolis track has same problem, only Neva is more severe) . It very well could be a conflict with the old cbash file that was created with previous build) Track is still fun though, just a lot of road reflection and some trouble with shadows now.
