Seems the plugin crashes if there are other events with an unrelated notetag...
I'm currently using Speech Bubbles by Nolonar, (https://github.com/Nolonar/RM_Plugins-SpeechBubbles)
which requires a notetag like this "<bubble:[text]>" for a speech bubble to appear over that event. But it looks like the Event Templates plugin has an issue with that because it ends up pulling this error:
rmmz_managers.js:2032 TypeError: Cannot use 'in' operator to search for 'bubble' in undefined
Is there any way to keep this plugin from freaking out if it encounters an event with a notetag it doesn't recognize?
