The White Wizard
I ran into a repeating CTD. The game crashes whenever I end the current turn. This is updated to rev 812. I started the game a few revisions ago, got the crash a few minutes ago, updated my current version, and still got the crash. Savegame and minidump files are in the zip.
Tracked it down. It happens in rare cases. When a civilization dies on a turn, and then a later civilization tries to asses the danger of nearby enemy tiles, it sees tiles that still belong to the dead civilization, and tries to calculate it's attitude with the dead civilization and blows up.
It's rare because dead civilization tiles are marked as owner-less tiles at the end of each turn, so it can only happen during the turn a civilization dies, and another civilization was at war with it, and whose turn comes after the dead civilization. Quite the chain of events.
All that was needed to fix it was to check that the tile owner was still alive.
