I encountered bug in 0.18.1 after Garden clean-up.
Since I'm very curious, I take a look at the source code. Hope you don't mind this. I believe the problem is that plot['crop'] is initialized as None, so the 'reset_plot' function will always fail at first. This completely blocked Garden related stuff in 0.18.1. A small None test would fix this. I've made a temporary fix for myself and it works fine.
