I downloaded todays build this morning, but still I was seeing -1 in stack traces. Shall I send you a repro project?
You can certainly try, but make sure that you have restarted GMEdit after replacing the plugin folder with a new one.
Ooops... I thought it was a GMEdit issue. Sorry. I updated the builder plugin and it works fine. (I have now added notifications for any change on that github :) )
