Journal items: "Help with 50 missions" and "Help with 250 missions":
We made an obelisk today on Pristine. There was a mission to make one. At the end, only the player finishing it got credit for these Journal goals, the helpers did not.
My character was at 78% done with "Help with 50 missions", and is at 78% after we finished the mission too.
Examine on the obelisk says:
Obelisk of Secrets
Ninjarubberduck: 688 (32.74631%)
Cambriaa: 116 (5.52118%)
Amath: 231 (10.994764%)
Tuga: 681 (32.413136%)
Wirano: 385 (18.324608%)
Tuga finished it, and got credit for the Journal task. (2% added to "Help with 50 missions")
I believe it was similar about a week ago, when we made another obelisk: I participated to it and I think I didn't get Journal participation recognized. That obelisk says:
Testimonial of Valrei
Ninjarubberduck: 343 (16.32556%)
Anarres: 34 (1.618277%)
Phoenixus: 147 (6.9966683%)
Amath: 521 (24.797716%)
Tuga: 805 (38.315086%)
Japiker: 251 (11.946692%)
As far as I'm aware, none of the participants except the last player got credit for Journal.
