I don't even know what triggered this. It worked fine, but then I wanted to add supply and shadow to some counters and it gave me the following error almost at the end of loading the graphics. I removed the changes (supply and shadow) from the .xml but it still gives the same error. I made no change to the other files so I'm somewhat puzzled by the result.

Do you guys have any idea what could trigger this?
