I'm using the tbin plug in for stardew valley map editing and the editor won't modify tilesheets... It gives the option to say "move a layer from the back to the front" but when I click it. It doesn't do anything it just leaves a the outline of the chosen shape in place.. Everything stays how it is... I'm sure it's probably something on my end seeing how I'm new to this... But as far as I know I did everything right.... Side question as it may or may not pertain to this issue: I was using tiDe but kept getting error when trying to load a xnb which I added tilesheets to.. Because I couldn't figure out how to add the tilesheets to yaml file.. Could that possibly be the issue why it's not modifying the tile sheets with this program as well, the yaml not being correctly modified... Here's a pic of the error I get when trying to load the xnb file back into tiDe.. Let me know if it's messing things up for this program too... Much appreciated... So far from what I see though Tiled is way better than tiDe... Good job man... 
I don't quite understand your issue, since the "move layer to front" action modifies the map and not a tilesheet. Also, neither Tiled nor tIDE use the yaml files, so I don't think the problem could be there. Could you report the issue and the steps to reproduce it at https://github.com/bjorn/tiled/issues? It's better to discuss it there.
