Zombie Runner - weird problems

Is there a way to get all the code written up to lesson 188? It was working fine until I started adding more copies of the zombie. Then it stopped moving, it stopped being provoked and all the zombies spawned at the same place (call it place_A). When I deleted the Zombie at place_A in the editor, it showed up back there when I ran the game!

If I add more than one zombie, they don’t show up in the game, except, of course, at place_A, even though I don’t put one there in the editor anymore.

Okay, I have another clue. The idle animation makes the zombie spawn at place_A. The attack animation makes a zombie spawn at place_B (sometimes).

Should I just delete all the animations and start over?
