We all know that sometimes we like to copy-and-paste screens for quickness. Well, if you do that, you can't exactly edit the new screen. Otherwise, you'll overwrite the old screen.
Okay, well, I just tested it again. It only seems to happen when you Paste All. I'm not getting much from this at all, though. ......
CONFIRMED!
this happened to me too, i pasted all, then i tried setting the layer that was currently on the screen to another screen(I changed the current layer screen
....and to my surprise, the copied screen has the SAME LAYER now!
Plus, if you copy a screen, delete that screen, and try to paste, you'll get nothing but A BIG BLACK SCREEN (Or whatever combo is set to Combo 0)! In other words.... When you copy and paste screens, the old and new screens keep reading from each other when getting data, thus causing them to be exactly alike in every way. This CAN be avoided by using Paste instead of Paste All. O_o
OMG, this is a deadly bug, I am lucky I was just messing with my test quest, because this is would have done some damage to my quest!
Anyways, I can confirm that this is still in (142). Even when you delete the screens, they will still be screwed up. O_O
I believe I see why this is happening.
Check more carefully - I expect you'll find the only things carried over are the combos, CSets, and flags.
I'll see about getting that fixed. Shouldn't be hard.
I believe this is fixed now. See here, though.
