Invisible robots in Automotron (Fallout 4)

Such is the bug of hell, invisible, but it can walk with me and talk, there are also several types of robots that are not visible.
Who can tell you how this bug is treated?
Z.Y it turned out to fix the fault turned out to be the mods for the companions after their removal went to the save game where he had not yet found the caravan and the voila everything is visible, everyone can see)))))
