Creatures Caves

Ok so I have been working on making my game work, it's finally in the right spot and passes a catalog test. I got so excited I stuffed it full of agents, cos files and breeds. Now it gets a lot of errors, doh! So I deleted the main problem that I could figure out (I think I stuck a c2 meta room in there on accident in my over enthusiastic haste) and it's not getting error codes every 30 seconds or crashing. And as long as i dont inject anything I don't get codes from improperly working agents (which I will sort out later)!

1) But... several of my breeds hatch with out the proper sprites,

2) my egg layer in the Norn room (not the DS one) always crashes if I try to scroll past the Aquanorn (I killed the agent and just use my Ds one). There are also two aqua norns on my list, and it crashes after passing the second. It's likely what ever breed comes after them that has the issue.

3) My DS one still has issues too, it pauses for long periods of time or perhaps its just thinking, when I pass certain breeds (same ones each time), I'm going to try to scroll through again and write down the trouble makers this time. Also, some breeds when I inject an egg, it says opening images for a very long time, and never makes an egg. Dodgy Norn is the one I can remember off the top of my head.

Question: Should I delete all the norn breeds and reinstall them one at a time like a noncrazy person, or is it some error with my egg layer? Also I believe the sprite issue is related to me having some of the mall breeds but not all, and perhaps those breeds that don't show up properly were based on the ones I am missing.

Question: In breeds that need to be hatched to unlock sprites, does the creature have to go through all the life stages or can I just hatch and not worry if they live that long? >.>

Oh finally, all my Norns are running around hissing like... I think grendels! meep! I have a back up untouched DS file, can I cut and paste the sound files to fix this?
