Several Russian Airports, in Moscow give the corrected QFE setting, as perhaps there is no need to correct a setting that has been read directly from the reference mesuring device.

Next time I will compare the advised QNH, and QFE. Expect optortunity tomorrow....

So does the problem only manifest itself in NON controlled airports, that are working on QNH settings.
It's the other way around. QNH is derived from QFE(measured pressure at the station) and adjusted by adding 1 hPa pr 30 ft above MSL. Therefore both will be equally accurate in terms of giving us a reference for our altimeters to give us either alt(QNH) or height(QFE), and the temperature corrections apply to both.
