A Major Update to the PlantSim Mod

When I was putting together my PlantSim Mod, I didn't fully appreciate just how unstable buffs (moodlets) can be. After 24+ hours of gameplay testing, I've fixed two major issues that have cropped up.

1) I made the PlantSim buff invisible. This prevents it from getting removed accidentally by UI exceptions, miscellaneous glitches, or user error (AKA cheating it away by mistake...which I did. Twice).
2) I fixed an issue where Sims who had been told the truth about PlantSims "forgot" that knowledge under certain circumstances. Long story short, I tied the knowledge state to a trait instead of a buff, so it won't disappear at random, and it will even persist after the Sim dies.

Please re-download the mod! These are major corrections that are necessary for gameplay stability. Let me know if you have any other problems!
