[2.0.9] Can't get steam achievements when playing co-op

[NasqwozDilemma]

I can't get steam achievements in co-op when playing with a friend. Noticed this after a friend played alone for a while and unlocked the green research pack achievement. After that, when playing together, he got an achievement with research with a gray research package, but I didn’t get the achievement.
