That will simply remove the ND and MFD from the aircraft completely (you will get white screens in the cockpit, which, if I'm not being too cheeky, is a great excuse to practice your reversionary modes). Like I said, I already had confirmation that the problem lies with the ND or MFD, but I would like to have more than one data point.
The first, extremely simple test would rule out one thing that I changed/created in the MFD map, but not the ND. If it doesn't fix the problem, then I will know where else to look.
Of course, it makes little sense that this is another problem in Starship that only affects some users, but that's software, I suppose.
