@fourscoopsplease I think you may have problems around not being able to save the state of a battle, and don't think you can have 2 battles running at once? (Never really looked in to it)
Perhaps you could reposition a chunk of grid cells for the platform since you have floating maps that aren't a contiguous grid anyways (like not one solid square of grid cells, only on the terrain moveable). You could get extra cells to generate with a temporary terrain piece and remove it. You can manually change Grid Cell Connections to have a cell move to another cell and Not move to it's old neighboring cells using Mode ->Connections, and or use a grid cell event for moving to/from the chunk.
That's all assuming you are making the grids/scenes by hand.
