Having the same issue over here. I scoured the zone about ten times today for this daily and I managed to find 8/10. I did not gather at all before the daily reset, and I waited as was suggested near trees in case of lag and them not appearing visually. There was nothing.
A very poor taste is left in my mouth regarding it; as above was suggested why not force spawn enough nodes for the daily to complete, in case the respawn system fails (which, from my experience, seems like it has).
