Wind is a common and regular enemy to most stoves.
You need to prepare your kit and site, in order to combat the wind.
For using a hexi stove, you need to prepare a shallow hole,
just slightly bigger than the stove. Remove the turf or soil and use this to form a wall or wind break around the stove. If it's really windy, as it has been lately then you will need to beef up the wind protection with what ever is to hand; logs, turf, rocks, card board or anything that will help stop the wind getting to your stove.
If none of the above is available, then move to a better site.
For lighting your stove, the issue "lifeboat" matches are often useless, even indoors! they have an erratic performance at the best of times. If you want to use these however, pack a few cotton wool balls in an air/watertight container to use when required.When you need it,fluff the cotton up a bit and light it with the match and then light the hexi; with the cotton wool.
an additional "helper" is to pop a little paraffin or kerosine on the cotton wool before putting it in your storage container. If the container is airtight, the cotton will remain moist with the paraffin but also become waterproof and will light up no bother.
Turbo flame lighters can be a better bet for lighting hexi in a windy situation but frankly; it makes no odds if you've failed to prepare a good stove set up, as the hexi will either blow out anyway, or you'll lose most of the heat due to the wind.
Honestly John, I wish you weren't as far down the country, I'd have been delighted to join you, for a day or two's "knowledge sharing"
I might have to sort out a video, of how we used to train our recruits and later on cadets, to use hexi stoves

PS: open moors usually have lumps of rock lying around that can be collected and built into a wall, perhaps using your rucksack to add to the windbreak.
