Fortnite | Fix Ur Game *Read Description*

At first i Couldn't pick up the small shields through the wall (witch you can normally do), then i tried picking them up through a window, but for some reason it thought I wanted to edit the wall, then I tried swapping to a gun, witch was my grenade launcher. I then tried to edit a gap in wall so I could pick up the small shields but it didn't let me, instead I shot the grenade launcher thinking that i was at the building menu. I fre'ked out and didn't edit out a wall in time, so I died. :'(
