I love gaming communities... thank you very much guys.
Edit:
Alright, so here are the results for anyone else who encounters this problem. This wasn't a perfect fix, but I'm not complaining.
I had finished teaching everything my creature knew on my last file, using the ape on the third land. After switching to the Tiger using the program suggested above, there were no glitches, but every miracle that my creature knew %100 dropped to %24. This makes sense given horrendous difference in intelligence between the tiger and ape. I shall just switch back to the other creature I brought to land 3, make that one the tiger, then switch back to the ape teach him everything, and then do a "legit" creature swap.
will update later I suppose.
edit edit:
by using the creature changer program to switch from a gorilla to a tiger, the miracles at %100 dropped to %74, again a proportional difference in the two creature's intelligence levels. I then had a tiger waiting to be changed to and an ape that just needed be shown each of the miracles one or two more times to regain that %30 deficit.
Many thanks.
