I don't know about the issues you've came across.
But, to be honest, on the performance side. I wouldn't recommend.
Some of us on the Construct Community, we were checking out your plugin on how it achieved it.
I didn't get to read it for long but as I recall, it loops through all the event sheets and events.
On Large Scale projects, it would take a very huge amount of resources just to look for a function.
When in fact, functions are supposed to be optimized to be quick referenced. And not search through the event sheets.
And the most heavy part of it is that it runs every tick. The performance overhead it provides is very hard and bad.
Good try though.
