thats a good 1700+ lines of code.
but i did remember seeing something in the manual and i just found it again:

[0] Camera movement. Switch between normal, direct player and camera movement.s

thats what the 0 key does in run, switches so that you can/cant move the camera. this works fine in run, but once it's published this 0 key function is disabled.

so i need to find what function this 0 key calls, or what it does exactly to get to the bottom of this.
