I noticed the screenshot they provided shows only secondary gathering points (harvesting, quarrying, and spearfishing). And from experience there is almost always a logging point in that area (just northeast of Bentbranch), which is not shown. Maybe they only show secondary points, which would make sense since there is no ability to find them.

I wouldn't mind if they put the one primary gathering point you're currently searching for (with an ability) on the map, though - even the full map.
