I don't think it's about the id limit thing. I don't remember LF2 throwing the a "couldn't create art surface error" for that. The problem, I guess, is that you're running out of memory. You're loading a lot of screen sized sprites which result in the error. Can you confirm that? Is that your case?

Yes, I use giant tables! Sorry for not having answered before

Then I can say that the A-GC will 100% fix your problem. Good luck.
