No problem, take your time.
There are a lot of changes yes. Which is why I just did some more playtesting. I just made another update
to 2.8.9 to fix ‘driving=true’, and a typo with the IsDefend missions, which will make them work again now .
here is the example of a zone for IsDefend (stop NPCs) mission… So you can make zones really large as well of course, by increasing the marker size and so the onscreen blip shows the zone to protect.
The zone markers I still need to tweak so they are always on ground level everywhere.
