I too have been working diligently. I have 1 MP left. I got it once in a different game that I lost but now it is evading me. I have several versions of the plant I need but no matter how many times I have crossed it, I cannot come up with it. I even looked at the spoiler that has a pic of all the MP's. The logic behind the charts that I have looked at seem to baffle me. I guess I am just dim-witted in that respect. The only thing I can say is chin up and keep trudging through. They will come up sooner or later. For us, it seems like it is going to be 'later'.
