It comes part and parcel of being in tier 5. We all used to bemoan the standard of referees when we were in league one and league two. The standard is not going to be any better the lower down the pyramid you go and is probably worse by default.
Like players there will be some good officials on their way up that will go onto to bigger and better things. Of course mistakes can be costly and it's annoying, frustrating and infuriating when these things happen. That's also why we need to be more clinical in games like yesterday going forward to rise above refereeing errors.
All the more reason and motivation to get promoted out of this league at the earliest opportunity.
