And this week, we have another prime example.
Celtic Crusaders final Northern Rail Cup group game against Doncaster had to be postponed because of a waterlogged pitch.
So when has it been rescheduled for?
Ah, that's the thing: it hasn't.
After due consideration, the powers that be have ruled there is no need for it to be played at all, apparently because "all qualification issues" have already been settled.
Now call me a fuddy duddy traditionalist, but I never realised these things were optional.
If that had been the case, then Matt Calland and his Halifax side would probably have decided not to bother with last weekend's trip to Whitehaven.
I am sure Calland, who rested eight players for what was a meaningless fixture in any case, would have preferred his team to have a weekend's rest before the serious business starts tonight.
Whatever happened to everyone playing by the same rules?
The decision to allow Celtic and the Dons not to bother is no doubt the result of trying to avoid fixture congestion around an already chock-a-block Easter programme.
Fair enough, except that by choosing this course of action, the RFL have given everyone in the National Leagues the perfect excuse to accuse them of bending over backwards not to compromise the Welsh side's league campaign.
With rumours gathering pace by the day that a Celtic side playing out of Cardiff are a shoo-in for a top flight licence in 2009, presumably at the behest of Uncle Rupert and his merry band of digidish salesmen, these are already troubled times.
The last thing the game needs is decisions like this.
Because, quite frankly, it stinks.

OF all the cross code traffic in recent years, a defection that occurred with the minimum of fuss is turning out to be one of the biggest losses to rugby league.
After Shaun Edwards' playing career drew to a low profile close with the London Broncos, the ex-Wigan superstar resurfaced as a coach in rugby union with Wasps, going on to achieve a string of successes with the Londoners, before becoming one half of the duo that has performed a sporting miracle with Wales.
Throughout all this, one thing has been clear: Edwards is just as good a coach as he was a player.
And why he has been ignored by the Twickenham establishment, whose offer of a part time job coaching the England second team was more of an insult than a complement, is simply staggering.
Whether Edwards stays with Wales or not, it will be interesting to see whether he eventually returns to rugby league.
My suspicion is that he will, and when that happens, there will surely only be one job for him.
That, of course, is at the JJB Stadium, coaching his beloved cherry and whites.
Brian Noble, watch your back.
