So there was an northern Irish official officiating in a northern irish teams game? That surely can’t be allowed.... I did think I heard an Irish sounding accent over the comms when he continually chirped in when Quins infringed but not Ulster.....

so there was one official, not the referee but one of the two touch judges was born in NI. Is that why Quins lost you're saying? If you take your blinkers off for a second you'll probably find that the Ulster supporters where equally not fussed on some of the refereeing decisions. Happens in every game. You see what you want to see.
Will be a cracking game at Quins, looking forward to it. Yes I'm an Ulster fan, but always had a soft touch for Quins since the Keith Wood days. Good luck to Quins in the Premiership old bean.
