LibGDX - TiledMap cutting off after each 33rd tile

Hi all,

Pretty strange problem here, I am reading in a TiledMap and parsing through the Layers then creating a Box2D box around the collision layers.

Problem is, it reads in the tiles fine and puts a box around them, but the 33rd box seems to just be ignored and then shifts every box infront of that along one.

It fits to the size of my camera fine but as I want the camera to be scrolling along the map this issues occurs. It seems to ignore everything 33rd tile.

Here's what it looks like.
