Looks weird for merging animation, it's because one of the tiles isn't refered as its origin by the merged one, so it won't appears. * Solution 1: Make a Grid with previous tiles of which animation is based with nextPosition instead * Solution 2: Make two previousPosition. It does what the original one does, however less stable (affects every new tile definition)
