Item disappear while following path3d

Question

I created a Path3D, added a few PathFollow3D instance to it by script, and added a VehicleBody3D to each PathFollow. It works well with the default screensize. But the items sometimes will suddenly disappear while moving in full screen mode. :rofl:

It’s a collision bug. Don’t know why, but sometimes the map doesn’t collide with item, so the item will fall because of gravity. Then item will be moving under map(earth).
