Since you mention it, apart from trying to scan the data and sell it in the same system, I also tried selling it in a station (since in my case there is one) and also in my own carrier that has Vista Genomics, but again nothing has worked, there is definitely a bug.Same for me. The weekly assignment this week, week 49, stated to 'deliver biological samples to <namely specified system.>'. The samples should be worth 332163 credits. I tried that several times but no merits gained for handing in the samples nor did the assignment proceed in any way
Two weeks ago I also had such an assignment, but that proceeded. While I was lucky that there was a fleet carrier in the system with exobiology installed and active..Other wise there only was an outpost, so no vista genomocs present. Which by itself is a stupid way to generate assignemnts.
I handed in in private group, but since powerplay is not open only that really shouldn't matter. Since there are no biological features in the specified system this week, I had to get them from a different system. Also it is not stated in the assignment that the data must be from the system the assiignment is tied to, which, again, would be a stupid way to generate assignments when there is nothing present to get the data, nor to hand it in.
On the other hand, at the beginning of PP 2.0 everything was going quite well, certainly the fact that many people rose in rank extremely easily since they had accumulated data is something that the developers did not expect, and at the same time that it was somewhat easy to rise from rank for some outside of the weekly assignments, I think it was not their intention, I think they expected people to depend on these and not other activities, and well, their solution has been a disaster, they have made it too complicated to rise in rank, in my case for the time I have to play, I only favored trading rare goods during the week, and I left the rest for the weekends, but now I'm stuck at rank 41 since I haven't been able to find activities with which to acquire a good amount of merits constantly, donating things like tritium can be quite effective, but very expensive and is not easy to find where to donated, donating credits is quite ineffective, trading commodities doesn't seem to work very well either, I think that selling one by one gives more merits than selling in lots, which is quite irritating, and now that the merits in the weekly activities have increased, they are broken or many are quite annoying to do like the ones in Odyssey settlements, anyway, honestly PP 2.0 was a good idea but very poorly executed, I think I'm going to avoid it while they resolve it properly, I'd better defend the earth from the titan's attack XD.
