[SUPPORT] Advanced Turn Based Tile Toolkit

Are you using the same indexes for each level? The index of a tile at level 2 is equal to the index of the tile directly below it + GridSizeX * GridSizeY, so for a 3*3 grid with two levels, the tile above tile 5 would be 14, for instance. If you want to display the tile indexes in the viewport select the grid manager and check PregenerateGameplayGrids and ShowTileIndexes.
