Also I got this error when my sprite collided with both a fully- and partially-purple polygon: https://gyazo.com/90cbfd84938845831d2d59492103138e
I'm not sure if it's a conflict or something else.

sorry this was an oversight on my part.. to fix this open the plugin manager, double click the collision plugin, choose the jump restricted regions, and delete all the data in it( probably just the number 1, ), then press enter, then click on it again, it will be properly formatted after that as an array of data.
