Objects glued together/glued to background corruption

[MrLucasManSwe]

Hi. I'm having problems with objects glued together (for example a rim of a car) and objects glued to the background (for example the track for the car) getting corrupted. It is moving around, ruining the appearance and function. It gets corrupted when the brush tool is being used on an object glued to the background, or when the object is moved. I explain everything in the video. Algodoo Phun edition had a similar issue when you moved a large group of objects that were glued to the background.
