Update:
It worked twice, and I have zero idea what made it work.
I uninstalled and reinstalled, tried with imported mods from the classic engine and new levels, looked at the message log to see if there was any type of error when
I used the mouse, same with the command stack history. I can only select/deselect or create/delete objects in the Eyes of a Child window, that is also the only thing showing in the command stack.
No answers on the internet either, I guess I'll just keep using the classic engine and hope for the best when I upload in the def ed for publishing...
