Trying to use change parent after I move a group of actor but when I set the parent parameter to NONE it makes the actors fly off the screen. Any way around this?

ChangeParent("Event Actor", "parent actor");

Tried. It doesn't make them fly off the screen anymore but they are still parented to the same actor.

So you are saying ChangeParent can't unparent things? gE uses "(none)" for the unparenting (though you should be able to change it to any name that isn't a real actor). When it comes to these problems I'd suggest making a new ged and just test out the function. If you can still make the problem occur in the new ged, post that and we can see what's going wrong. Otherwise it is something in your setup that you aren't remembering.
