Hi,
found a bug with the Action Editor... it leaves some junk after an action is removed from the entity. For instance, if you add an AI sensor to a mesh and then you remove it, some tabs stay in the properties list and there's no way to delete them. Also happened with the Camera V2, the SCC, the Weapon Attach and some others.
Additionally, the External Script property dissapears from the list when you remove any of the above mentioned actions.
happy new year everybody...
