Basically, everything works fine until I attach an event sheet.
Once that is done, it's throwing this error.
Attempting to debug the issue.
1.) Created a new project, added a few globals and "on start" event to the default layout sheet. No error.
2.) Using the new project, I made a debug sheet, swapped the globals and on start event to it, attached it to the default layout sheet. No error.
Error isn't popping so that means it has to be related to my project, I'm assuming.
Fixed the issue.. Not sure why it was throwing an error for Spine though but whatever.
