I am not sure if I am doing something wrong but whenever I load a map with MTE everything is totally offscale. Some sprites are much smaller than in Tiled, some are more or less the same. Some objects are a lot more far away from one another than they are in Tiled, some look fine.
This screenshot really explains everything:
