I'm currently working on a new episode for SMBX 1.4.3. I've pretty much finished all the custom graphics, and decided to test them out. Once I save a level to start testing, however, I get a runtime error. I have no idea what could be causing this. It works fine with other levels, either downloaded or from another episode I'm working on, but I just don't know why it would be happening for this specific episode. Could there be any corrupted graphics or txt files I might have copied, or are there too many graphics? (even though I'm trying to reduce them)
