v0.23.1 - Improved scenario editor

v0.23.1 brings some minor fixes and improvements to the scenario editor:

• You can now move individual nodes by default, or use SHIFT+CLICK to move the selected node and all subsequent nodes as one solid block

• You can open broken scenarios so that you can fix them in the editor

• There is a little preview of the funnel shape so you can tune bottomRatio to any reference footage you have

• You can toggle the game's tornado track overlay with space or by clicking the 'trail' button

• Fixed tornado formation in scenario mode so the tornado doesn't suddenly appear

• Multi-vortex options are now available in the editor
