"Sprite outside of..." error

[SwissGeorge]

Hi there,

I'm trying to put together a mod that will add a series of higher-level transporter belts. However, every time I run the game, I get the dreaded "Sprite outside of" error (attached). I've quadruple-checked the folder names and file paths, and all seem to be correct. When I instead initiated the graphics files by calling __base__ artwork and re-using basic-transport-belt sprites, the mod launched just fine. For the life of me, I can't figure out what the problem is. Any ideas?

Somewhere along the line you've changed frame_count from 16 to 32, so Factorio is wandering off the image trying to find these extra frames.

Amazing! Thank you so much, that solved the problem completely! Now off to build a super-factory!
