Thank you so much! I'll give that a shot. I narrowed it down to my slices having different sprite numbers for some of the animations (mostly the fishing Sprites)
I'll give the pre-sliced ones a shot and see, because while I got the fishing animation working, I was still getting the error. I'm guessing it's because I didn't leave empty sprites in place when slicing and it probably shifted the indexes all around.
One last bit of feedback, in the tutorial I believe setting the anchor points for first row and second row on page 3 should have the images order swapped.
Thanks again for sharing this! It's super helpful.
