If you enter commander mode and begin to place a building, but exit the command vehicle without dropping or canceling the structure, then open engineer menu to place a structure, the commander 'ghost' object will cause a visual bug. Steps to reproduce: * Spawn as Engineer * Enter command vehicle * Select the wall tool and mouse over the map surface * Exit the command vehicle without canceling the structure placement, nor placing the structure * Switch to engineer too * Open engineer menu and select a structure - for example supplies * Observe that, in addition to supplies, a "Ghost Wall" placement indicator will appear.
I'm not sure if you're trying to say the ghost placement indicator is a feature of engineer tool (it is), in which case you haven't understood me. The bug I'm referring to here is that, rather than have one "ghost" indicator for the structure you select, the commander's ghost indicator state bleeds into the engineer's build state, and two ghost indicators appear at once.
I have a screenshot on steam somewhere of all three, I'll find it and edit it in soon edit: it's turret+wall+ammo
I wonder if getting killed while placing a wall would cause this as well. It seems like something fairly common which might explain why most often this bug is reported as being a ghost wall
