Ok, so I just talked to the tech guys at the store Apple Support told me to contact and they said that the instructions they've got in this case is for me to take the MBP in when I know the bug is triggered and they'll do a specific test to each hardware component, send the report to Apple and they'll tell them if and which component must be replaced. So, now I just need to manage to trigger the bug and take the MBP in. If I'm able to trigger it lol. It is unbelievable that, now that I want it to misbehave, it won't
