I've been playing the game for the past week and have noticed several problems with the current build.
1. You can build multiple 'unique' buildings such as capitals or the ideology buildings by queuing them on multiple planets simultaneously. As long as you don't have one complete, you can add them tot he queue of as many planets as you want. I don't exploit this, but I think it should be fixed.
2. Wealth is useless. I put 100% of my production into Manufacturing and Research. At some point, I'll get Interstellar Tourism and instantly have positive net income and never worry about money for the rest of the game.
3. Artifacts that instantly finish projects or research, often do nothing when my production queue is empty or has an ongoing project such as Birthing Subsidies. The worst is when I've just finished a tech, get the free tech and I haven't selected a tech yet.
4. Ship Designer is poorly designed. After researching a few weapons and hulls, dozens of generic ships appear in the ship list including duplicate M0 designs in addition to the most recent M6 design. Manually obsoleting them is tedious. Also, player designed ships are too easily deleted, can only be deleted, and are in the way whne you can't obsolete them.
5, Graphics freeze occasionally on the planet screen, tech screen, ideology screen, and event screen.
6. After starting too many new games, random white bars appear whiting out important text in tool tips and event screens.
7. Repeated game crash exiting to desktop when managing a Barren World.
