Okay, so what's happening is that I'm trying to work on a map but every time I type the file in to load it the game crashes.
I made another map to see if it would load it, that map worked fine, so I re-exported the other map file but it still crashed.
I've restarted my laptop - still didn't work.
I've remade the map - still doesn't work.
Test map still works.
Maps are .PNG files.
They are both the correct size.
They are both in the feralheart/media/terrains folder.
My map that does work.
Map that doesn't work.
