v20.1 Voltseon's Overworld Encounters v1.1

It works great! I am curious though, is there a way to turn OW encounters on and off through an event for cutscenes?

A really great plugin to use for a Legends style project. Though it would be great if the plugin could also work with the Automatic Level Scaling plugin

Pokemon don't spawn on the overworld and trying to open the options menu crashes to this error:
