Weeks ago I discovered I can duplicate the Lighting class using copy and paste instead of Ctrl + D
So, thats really annoying because classes like Lighting cannot be duplicate and well if you do this ,the duplicated one can’t be deleted and you need to restart the world to delete them
Expected behavior
Trying to delete the duplicated lighting but I can’t do that so you need to restart all your work
If you need a better workaround for this, you can set the unwanted Lighting’s Archivable property to false, and it won’t be saved the next time the place is serialized (either Team Create server shutdown or Save of a non-Team Create place).
Setting Archivable = false on something tells the engine “this is temporary, do not save it”. It is normally used by plugins when creating temporary Instances that the plugin does not want being accidentally saved into the file.
So, do that for the Lighting which you want to go away.
