Hey,
I'm having some trouble with the map I am currently working on.
First of all, when I start the game it will sometimes start with NOTHING in the world, and the location of my guy is in the far bottom right corner of the map. Since I put in a few more spawn rects the problem isn't quite as bad now but still happens every so often:

Do the spawn rects have to all be located inside of the base rects, or can some sit outside of them? Starting a new game usually fixes this.
Secondly, I'm trying to put in a platform. I have had success with most all of the ones I have put into the map, but these are really finicky to get working right... Why is this happening?

Is there a particular size, and length that platforms should be? The settings are identicle for the two platforms shown in the second screenshot, but the length is not. They are both on flat ground as well.
