I'm pretty sure they're referencing the API script I created for the 5E Universal Statblock MacroMule , and yes there is definitely an issue with it, and I'm pretty sure it's because of how I have everything in the on("ready") event, instead of done in any kind of better way that requires more understanding of how to properly code in Javascript. I simply modified Marco R's script for creating a Loot Macro Mule to create a Macro Mule character of my own... but I'm sure there are best practices that weren't taken into account when I changed things. I've noticed that if my MacroMule script is before any other scripts, those scripts don't work correctly - I'm guessing because it's not passing along any code that it doesn't use correctly when it's done with it or something. I honestly don't know how/why that would be that way, so that's just based on my limited understanding of javascript. I've found that scripts will work if I delete the MacroMule and re-add it as the last script in my list.
