So I'm trying to make the change from the old sphere to miniSphere, but I'm old, I hate change and somethings frustrate me to the ends of the earth.

Anyways, I think it's a bug, I'm using miniSphere 5.3, and working off a blank tileset and editing it as I go. I frequently load up the game to see how things look and try to see proportions of the surroundings. The problem is that in the editor it updated to the newest iteration, but when i test the game it defaults to an old version. I've tried closing the map, and the project itself.

The top part is cropped from the editor, while the part below is being ran from the engine.

Is there something I'm missing?

Since it's minisphere; it's likely an issue with Cell, the game 'compiler' system, which is supposed to compile your assets into a distribution folder for release. In this case the 'dist' folder has an outdated tileset.
