Gravity is removed in order for new vehicle physics
Better vehicle physics but flying vehicles will be removed. Just an assumption with the last update adding shaders and removing maps.
We abandoned v##, we now work with revisions.
wasn't there revisions during v20?edit: yephttp://forum.blockland.us/index.php?topic=176638.0before v21
Once Badspot coded brand new amazing vehicle physics, he had to destroy it since the game can't run amazing vehicle physics if it is running amazing vehicle physics (the ones he just created).
