Vehicle issues since the last couple of updates

[Bobcatt]

Steps to reproduce

1. trying to drive or fly any vehicle on the grid

Expected behavior

basic operation had fair number of scripted vehicles operating on this grid but now not even basic scripts are working

Tell us what should happen https://www.facebook.com/166228873398171/videos/1070011513019898/

Actual behavior

Tell us what happens instead
Car based scripted vehicles refuse to move other than rotating on the axis back or forwards when the up or down arrow keys are pressed. Aircraft just thrash violently on the axis and either go screaming off the end of the map usually to the east or rocket up into space while violently thrashing/rocking/tumbling. Spent fair amount of time picking though scripts to see if something had gone wrong with them but test show they function fine and were working normal before the update..
this does not change even if the vehicles all prim, sculpted prim or mesh all fail.
Now getting these messages after start up of the grid they randomly show up but might be part of the issue but they showed before vehicles died.
