Hi *
well first of all, I'm not sure it's 0.18.10 but it's a the very least 0.18.x
Can't get the factorio version without beeing on start screen, and leaving a game reset all planned deconstruciton so I'd rather pass rigth now.
into the facts :
Mouse deconstructing (rigth click) shouldn't work when using the radar, except for gosts. Not sure if it's wanted but for all it matter that seems to be the defualt behavior of the game.
What's happening, is that if you first mine (all under radar use of course) a ghost and the keep your mouse cliked for further mining, then you can mine anything. Trees, existing building. I guess ore too but I've not tested it.
it's quite visible when done with range extender mods - but because you still need to get in range it's not game breaking.
it's easy to reproduce so I will afford myself some lasyness and skip screenshots. If you have issue reproducintg it I can upload some tho.
