Well, I've learned how to live without the undo as well, but come on, why should we have to learn to live without something?  They should fix the problem.  But aside from that, I just noticed that the ecosystem in question somehow replaced one plant with another and that that is what's causing this problem.  Oh well, I'm done being angry, I'll just redo it.  Luckily it wont take long with this picture.....
