Turns out Yoyo listened to the feedback about people getting their workflows destroyed by deprecating that one debug function, making the version 4 source code I rushed out pointless!

I've removed the version 4 source code again and re-released the previous version (which was more stable and convenient), if you're working on a game using my engine you can just ignore the previous warning and not do anything with the in-game editors - they'll still work in the future. Hopefully you didn't already invest any time in trying to work around these functions that were going to be removed but now won't be anymore...
