[GDExtention] Fails on first load after clean build

Weird issue that only started happening today, Akien thinks this might be an upstream problem but we need to investigate it further.

First time I compile the plugin from scratch and start it in the editor, the editor doesn't recognise the classes. You can see in the logs its initialising things to late.

Second time running, or running with a breakpoint set, it all works fine, so its definately a timing issue. Also from that point onwards it keeps working so it must be caching something about the library.
