Okay, so...weird bug: Any flower that drops when you shake trees freezes the game. You can save and log back in from where you left off and have the flower in your inventory, but it's also still where it dropped from the tree. It's annoying, but lets you get infinite flowers (if you don't mind logging back in repeatedly).
Whoa, I have a renegade rose garden that dropped. Everytime I click on it to pick up the game locks up. XD So, I think I'll just avoid it from now on. Thankfully, it doesn't stop me from saving and starts back up just fine.
