So the good news: it doesn’t crash on my end! 🙂
Btw you should be using the same size as the character for every item, as they are rendered on top of each other, so if the sizes don’t match, the positions won’t be correct. The Season #2 bases are 1010×1200 pixels.
A question though, I assume this is the first category where you actually have an item, how does your .bat file look like, what parameters are you using?
