No Lon-read the crucial part of the answer above that you have ignored-it was NOTAMED closed but traffic was allowed through when the 2 valid staff were there. The alternative is that the NOTAM has varios closing times on it and the routes become almost impossible to accurately portray on a FPL if an a/c is running late. Much better to do what they did and allow traffic through when possible.
It's still a far from perfect situation and the sooner we are adequately staffed at night again the better.
