Hello,
I updated my NGUI scripts through the asset store and I am now getting the following error after i stop playing a scene in the editor: Scene is being destroyed while there are hidden renderers that are using it. This is likely an editor script creating objects with hideFlags and leaving them enabled.
I've also set up 4 sprites, who's spriteName i change through code but for some mystical reason the old sprite doesnt seem to disappear anymore. Prior it would update fine.
[Edit] after some toggling some things on and off it almost looks as if NGUI is caching the graphics or something silly. I toggle off a huge part of the UI and then on play, as if by magic, that part of the ui shows up again. But i can't select it in the editor.
[Edit 2] Turning more things off and deleting things while running it left something like a cached image that i couldnt select. It was even there after deleting everything in the scene which led me to assume it was a Unity error of some kind. A quick restart seems to have cleared it up.
When in doubt, reboot.
