Comment incorporated. Separated them into two separate projects and released an update.
It seems that when you did that it also prevented installing The Archmage via the client.
Strange. I'll take a look. I uploaded a new file. Maybe that's causing a problem for some reason.
It works in the browser, but not the client for some reason. I tried a fix for the client and it now works, but I'm not sure it's because of what I did. I need to learn how to use Butler. I know that will solve the problem for the future.
