Good work with optimization, game runs much better now. I'll point what bugs and glitches from my previous thread I still encountered: 1, 5, 6, 8, 9, 11, 13, 18, 19, 21. 23.
1. There is this anomaly that instantly builds an improvement, unfortunately it also targets projects which means it gets wasted.
2. Ships bought from the AI get displayed in the ship list with their original civ colors.
3. In the treaties list after trading for a ship it gets displayed as New Game.
4. Ascension Crystal and Elerium Node in the same tile.
5. It should be more obvious what the destination of a shipyard is. I can't find the info anywhere in the manage screen.
6. I still think tourism is OP. A solution I can think of is to reduce the output of the current improvements and add some new buildings that can built multiple times on a planet. Essentially you would have to specialize planets for tourism to get similar values to what is now in the game.
