List of Achievements that I am hating:
Advent Harmony Researcher - did the bloody thing twice to no avail D:
_____ Lender - I'm pretty sure it really does mean 'player', not computers.*
Pirate Exterminator - I killed at least 5000 pirate ships last night. I hate you all.
Space Ponies - because Space Ponies.
I thought I had problems with Go Big or Go Home as well, but supposedly I got it at some point.
In other words, I am sorry.
*GoaFan77 achieved the Lender achievements loaning to AIs in single player mode. I confirmed during Beta 3 that these DO work with AIs.
