Idk if im bad at this game or i just do some errrors, i´ve tried 7 tutorial alr, tracks keep falling out, they are really laggy, or just broke because they want, idk dude.
where does it fall off? if during driving, then try to fix the spring connection, if trying to set it up, try reducing speed of the pistons that set the tracks in place or split the 2 pistons that move the track in place to 2 separate switches instead of 1
