I do not know if it is the correct area to post beta bugs, but if it is not, please move this post to the correct area.
Sorry for any inconenience and terrible English.
Before update my A6 to 6.40 all work fine, but after this, the car fall in the terrain .
The terrain is using the newton terrain, but I try use the terrain with not preferences and the problem exist any way.
In this image, the truck fall in the terran an go to undergrownd.
I do not know if it is a bug or in this new version need any paameter to set the ground colision with the car.
best regards,
Marcio
