After playing with v1.5 opt-in through the weekend please find below findings:

• Exploitation of the AI when offering exploration treaty is still valid supplying the player with the lifting of FOW as well a huge amount of money. Re-balancing of the treaties values is not visible here. The value of exploration treaty needs to be cut down considerably (almost all CIVS give all their money for this and it expires quite rapidly.
• Non-aggression pact is the same as above though not that exploitable. AI should not give any value for this when in good terms with the player (why would it pay to have this if there is no tension? Currently it works as a tax for friendly CIVs
• Breakdown of moral shows a value titled "Missing Info (6) +0" - might be a leftover form large empire penalty
• Final UP vote on "Galactic Domain" act still does not show resolution. Both options are red and no final verdict displayed
• Embassy text claims to have influence bonus but does not list the effect in its desc. When looking at breakdown of planetary influence there is a category called "Consulate" but might be referring to something else
• Tech treas are referencing to default CIV names instead of the custom CIV name. Need to change fix text to variable to reference custom CIV race name. e.g.: "Defense Meditation" return text for "Altarian" race independently from custom CIV race name
• Diplomatic act to have AI starbase destroyed in player territory needed like the AI has as the AI still does not destroy their unneeded bases generating costs for them and hogging the space from the player.
• Requesting AI to move away ships seems to be working but is a bit strange as it gives a diplomacy penalty if requested independently how the AI reacts. Can the AI refuse and does this automatically mean a declaration of war? Not clear from desc. Does the player risk war when requesting it?
