* When the player tries to pay an AI civ for war, the trade screen no longer says "Maybe we'll change our minds in a few years" when the AI is almost willing to agree. I figured this gives away a bit too much information. * BUG City Cycle Arrows disabled because they crash the game and I can't figure out why. It works in K-Mod, so this is somehow my fault. In an attempt to fix the issue, I've restored the signatures of several exported DLL functions. Didn't help, but I'm keeping the BtS signatures now; it's safer. [advc.042, advc.003] * On Noble difficulty and higher, the AI no longer demands things of little value as tribute. E.g. won't demand a bonus resource in the Medieval era. [advc.104m] * Reduced the research bonus from Raging Barbarians. I had added this in v0.80 to keep tech in games with Raging Barbarians closer to the real time line, but it was a bit much. [advc.308] * 10-turn grace period for revolts in newly founded cities now only applies during the Ancient era. [advc.099c] * War-on-friend diplo penalty corrected (was still not right in v0.88rc) [advc.130h] * Rare(?) bug fixed in change advc.040 that caused a crash on maps with land near the poles. * Fixed an issue with an earlier change to AI Auto Play - sometimes, it ran endlessly if started after switching to another civ. [advc.127] * Some misc. tweaks in UWAI code. * Can adjust UWAI war evaluation through AI_Variables_GlobalDefines.xml. [advc.104x] * Added an assertion that checks if integers from XML are loaded successfully. Found and corrected a couple of unimportant errors this way and changed some game initialization code that had been trying to use XML data before it was loaded. [advc.003c]

| <!-- [advc.104x] This file used to be called BBAI_AI_Variables_ | ||
| GlobalDefines.xml; now also contains UWAI parameters. | ||
| UWAI breaks down the computation of AI war utility into a sum of | ||
| 26 "aspects", most of which are either in favor of war (added to the | ||
| total war utility) or against war (subtracted). There are a few mixed | ||
| aspects that could either increase or decrease war utility. | ||
| Each aspect corresponds to one particular motivation for or against war. | ||
| Through this file, a weight is assigned to each aspect. This weight is | ||
| interpreted as a percentage by which the aspect utility is multiplied. | ||
| The default (recommended) weights are all 100. This doesn't imply though | ||
| that all aspects contribute equally by default; the weights are only a | ||
| final adjustment to the (hardcoded) formulas. | ||
| A weight of e.g. 50 halves the default impact of an aspect, 200 | ||
| doubles it. 0 means that the aspect is entirely disregarded. A | ||
| negative weight (not recommended) turns a pro-war aspect into an | ||
| anti-war aspect or vice versa. | ||
