So in the latest update some names of items were either changed or taken out entirely and was used multiple times in one of my missions.

Now that this has been changed I get multiple errors about object not found not a real issue as I can still play and edit the mission. but it would make life easier if when this error came up in editor we were presented with the option to delete this entry from the map this would make life easy for us if there are more changes like this at any point in the future.
