Hi there, Jarred. This kind of problem is almost always caused by users moving or renaming tileset files.
A couple of observations:
You say the tileset is named base_tileset
But the errors says it couldn’t find C:\base Tilteset.tsx
So, it looks like there’s some problem there. Can you open your map in Tiled? I would expect it have a hard time resovling the tileset reference as well.
