Plug connector shifted by 1 position

Hi,

What can be damaged if the plug connector (between the main board and the filter board) has been temporarily wrong connected - shifted by 1 position during operation for 1 or 2 seconds (5V pin of mainboard hangs in the air and 5V from Filterboard goes to ground-pin and ground from filterboard goes to osc-pin aso.)?

I couldn’t notice anything wrong now - it still works after I fix it.

I’m certainly not the first person to have this happened.

Best regards,
Rio
