Post patch 1.5 Bug List

[Servius]

9) Some techs, like Interchangable Parts, become available for research before the prerequisite techs have been learened.

10) The diplomatic penality "Territorial Expansion" still does not decrease if you lose or give away territories. This creates a situation where, if you help your ally recapture of one their regions, and at the end of the battle you have the larger force, you'll get the region. You'll get a penalty for taking the region. If you give the region to your ally. You'll continue to suffer the diplomatic penalty for taking a region you no longer control. There is also no diplomatic credit for giving the region to an ally. In the end, your ally will like you less for helping him recapture a region and then giving it to him free of charge.

11) There seems to be a problem with how the AI values land swap deals. As GB, I was helping my ally the Ottomans by retaking regions they lost to the Prussians. I retook Turkey, Iraq, and several smaller regions. When I tried to trade Turkey for Egypt, or Iraq for Egypt, the Ottomans refused. When I sweetened the deal with 6 techs and 20,000 gold, they still didn't agree. Turkey + 6 Techs + 20,000 gold is definitely worth Egypt.

12) There also seems to be a problem with how the AI values protectorate offers. The AI used to make seemingly rational decisions prior to 1.4. I could offer ~5,000 / turn for 20 turns or less and get nearly any nation as a protectorate. Post 1.4 (or at least 1.5) I can't get a protectorate to save my life. I've offered 20,000 gold at once + several techs, or 5,000 gold over 20 turns (100,000 gold!) + several techs, and none of the nations took my offer. These offers were made to nations that were Friendly towards my nation as well. That seems outrageously irrational, which is why I'm listing it here as a bug.
