Thanks for your quick response.
This does not happen on native exports, but I really need this to work for HTML5 exports. No clue why I didn't check my console... It's throwing the following error:
Runtime error: [error] Script index must be a number, got `instance#1000003(oChatController)` (struct).
I found one comment mentioning this issue on your post on the YYG forums, but the fix/workaround does not apply to me in this case.
