Fix big moving vehicle builds from disappearing from the world

Whenever I try to make a big moving vehicle build on tracks, it will most likely disappear from existance sometimes making the tracks it was on disappear too. This is a very frustrating glitch as it makes builders not be able to make certain builds. Please try to fix this thank you.

Start by reproducing the behavior described in issue #7: build a large moving vehicle on tracks and observe whether the vehicle or tracks disappear. Use the linked video as the reference for the failure. Done means the vehicle and its tracks remain in the world during this scenario.
