AGS debugger stops game when using ScriptFunctions plugin

[persn]

1. Add Plugin to AGS
2. Enable plugin to a game.
3. Add the function Test() somewhere it will be executed on run.
4. Run game.
5. Once the function triggers it will display a couple of text boxes until the AGS debugger stops the game.

Error message: Invalid message number to display

ScriptFunctions is a demo plugin that showcases how you fetch AGS API functions and use them in C#. I suspect this error is caused by the an API call being obsolete in my version of AGS.

I'm using AGS v3.3.3
