Hi Commander,
Thanks for the updates.
Since ‘BugReporter’ has already “Closed” this issue, I think the best path forward would be to create a new bug report. (Citing the attempted 30.40 fix and demonstrating that it’s still an issue.)
This could be a situation where the interplay between Vehicle top speed, Movement Modulators, and Autorun would require major changes/rewrites to one of those systems…
