Need help! Weird CycloneII LED assignment problem!

Hey guys, My pins on board don't work as what they should do according to pin assignment. In my design entity, I have outputs LEDR0, LEDR1... LEDR5. I assigned them to correct LED pins, no...

Strange indeed. Are you sure, that the pinout file refers to PIN_AC21? Is the LED also driven in other design or for an unconfigured FPGA? Sounds either like a hardware defect or a strange Quartus bug.
