Winterberry Nodes
Sounds like each pair is implemented as a node farm like the flax farm in VB. Maybe because there aren’t any t6 nodes that are gathered with with a sickle except for the farms.
It is also fairly easy to avoid … just fully harvest each before moving on.
Briefing: If you can re-harvest one winterberry-node (1), but then switch to the other winterberry-node (2), both nodes will be depleted.
I have noticed this frequently for a few weeks now (after some update), it is true.
I noticed this with the flax farm in VB I think a month or so after HoT came out and has been on and off since then for me. Made a bug report then, I just assume it’s hard to nail down since it’s kinda random. Not sure if I’ve seen it in core tyria but I know I have at least at one point or another seen it in every other new map that has a bunch of nodes close to each other.
