I harvested something like 700 shadow nodes on Thurgadin, and several times, we were at least 3 players gathering at the same time in the same area. I never, ever, had a run with no shadow nodes at all. Sometimes 2-3 nodes and that's all, but never zero. On Test, we were 4 players in the Blinding when I tried, 13 on the server and I got no node at all. Several times, Niami and Suzeta complained about having no shadow nodes showing for them either. I gathered 700 nodes, I know what they look like, I know how to do it, there's no competition on the server, my particles are set the same way as on live when I gather. Everything points to a bug specific to Test server: zone going down, respawn breaking, no regular harvests harvested in the zone which breaks the respawn for shadow or something weird like that, but there's something specific to Test that needs to be looked at.
