From Jay: Yes, there is a limit of how many things can be in the same purchase menu. But the only thing I actually tested was the number of things in the scenery purchase menu, and that limit was 3000. It is possible that different purchase menus have different limits. It is also possible that young animals count toward the limit in addition to adult animals, or if the female graphics are different than the male graphics that they also count toward the limit. But I do not know because I did not test this. Also when I tested, it was with the original ZT, which did not have purchase menu filters. It is also possible limits changed when they added the purchase menu filters. And I cannot rule out other problems. There was the problem with the animal info when the bezoar goat and scotts horse were in ZT folders at the same time, even though they each worked when only 1 was in ZT folders. I never got around to figuring out what caused that. And since I do not know the cause yet, it is possible whatever caused that is causing other problems.
