I uploaded another version now.
Basically, what's happening is that when someone finds a bug that break's GMLive's compiler, or when I'm experimenting with something that involves changing how compilation is handled, I enable a flag that adds that line (showing the script chain that executed before yielding a compilation error) and one other. Then I sometimes forget to disable it before uploading and you get this. I have now stripped it out for good because I think this is the third time this happened.
