Impossible Achievements

Hi,

I was wondering if the following achievements are currently unattainable or near impossible for the following reasons:

- Privateer: Used TEC Primacy planet item to build well over 50 supply of pirate ship and achievement didn't unlock.

- Military Intelligence: Only researched military topics in a match victory but achievement didn't unlock. (This achievement could also be understood to mean research ALL military topics, but without exotic refineries it seems a bit ridiculous so I'd assume that's not the case?)

- 4 Ship/Planet artifacts: I've tried a few times on random 10 player multi-star maps (against a single enemy empire) but haven't been able to collect more than 2 planet or ship artifacts across my empire at once. Am I missing something?
