Please report all single player bugs and crashes for the SVN version of C2C here. (release v39 = SVN Revision ???) If you are using the download version of Caveman2Cosmos v39 please use the other thread. However, you will likely need to update to the latest SVN version (at least up until we break compatibility) to get a chance to verify that the bug is still in place, and to be able to easily get an update that fixes the bug afterward, so you may want to first get the latest SVN version if you can before reporting a stock v38 bug. To assist us in fixing the problem please include the version of C2C you are playing. If the bug involved a repeatable "Crash to Desktop" (CTD) or similar please include a save and description of how to reproduce the crash if your mods folder is not Caveman2Cosmos please state what it is when posting a save to help the modders and save them time when trying to identify the problem. the MiniDump.dmp file. It is found in your Beyond the Sword folder that contains the Mods file containing Caveman2Cosmos. IE the folder that contains the BeyondTheSword.exe file. If the bug includes error messages then the Python.Err file in the logs folder would be useful also. It can be found in the same location as the the Saves folder containing your save games. A screen shot. Basically as much information as you can that will help us find the problem[/INDENT] If you saw the AI doing something stupid/unoptimal/otherwise bad make sure your BBAI logging is set to 3 in the BUG options. Then, post a savegame exhibiting the behavior as well as the BBAI log, found in the Documents/My Games/Beyond the Sword/Logs folder. How to turn on logging. In the Civ 4 INI file, located in Documents/My Games/Beyond the Sword, there are some logging options. Make sure they look like this. Code: ; Enable the logging system LoggingEnabled = 1 ; Enable synchronization logging SynchLog = 1 ; Overwrite old network and message logs OverwriteLogs = 1 ; Enable rand event logging RandLog = 0 ; Enable message logging MessageLog = 1 Note: You only need to have RandLogs on if you are playing Multiplayer, otherwise just leave that off (thx Cyrusfan) How to turn on the AI logging. The AI logging is turned on in the BUG options screens. It is the BBAI log mentioned on the Logs page. It writes to the same folder as the other logs creating a BBAI.log file there. Known issues If you are playing on Windows 7 and get a crash, play in Win XP compatibility mode and you might get past the crash. There are still some possibilities for crashes in the unit combat animations. Try turning on the fast combat options in the main Civ IV options panel and see if the turn gets past that point if you have crash troubles and you're allowing combat animations to show. We THINK that these have largely been cleared up but there's still some potential for it I think. Some air unit animations are still disabled as a result of known crash bugs there. We have some known spots where we have some pointer problems that can cause crashes. Those are getting as fixed as we can get them before we break compatibility so we'll have to really make the compatibility breaking updates very apparent when we hit that point soon.
