All I can say is that your drive sprockets is likely the cause of the tracks coming off but nevertheless make sure they are tight and snug. That being said I paid more attention to the idlers. All I did was made sure the idlers did NOT wobble even slightly. I used simple scotch tape and taped in around the screw/axle then I shoved it in the idler making super tight! Once you do this though you you'll notice your first run will be noisy and a little tight..but don't worry, the friction will melt the tape in place and then boom there you go problem solved!

I've done a lot of testing and taking apart here and there, I can stand confident on this, hope this helps everyone with this problem.
