Agreed. I don't run VD, ECS or Blue Marble and I get crashes without opening WB. This has happened since the addition of the Moors (SVN 391) and still happens on SVN 397/399.
The crashes cannot be consistently reproduced, i.e. when I load a save file and press End Turn, sometimes the game will crash, sometimes it will not. I've tried a variety of things, including:
(1) Rebooting Windows;
(2) Disabling Autosaves: I find that these crashes seem to happen more often on the turns right after autosaving;
(3) Artificially removing civs and cities from the WB: Since these crashes started happening to me after the addition of the Moors and escalated after the addition of Kongo, I figured there might be too many civs/cities on the map;
(4) Removing/avoiding certain Wonders: I have an American game where it becomes crashy only after I build the Empire States Building. Cristo Redentor also appears bugged, as it's unbuildable in cities with Catholicism even though I have Radio;
None of these seem to completely decide whether the crash happens or not. It still appears random (although in one case it seems to depend on whether I make peace with France or not - if I make peace the game crashes. If I don't, it slows down but does not crash. No idea why.). I'm not getting a single Python error either, even though I enabled Python exceptions.
However, even when the crash does not occur, the turns become excruciatingly slow. The game would be stuck on "Waiting for other civilizations..." for more than 20 seconds. Then it would either suddenly snap out of it and proceed as normal, or crash to desktop.
I still think the primary culprit are the Moors and Kongo, or more generally SVN versions 391 and after. I never got crashes of any kind before 391.
P.S. In my Moors game (the one in the 1.9 UHV Challenge thread), the crashes seem to start after the Turkish spawn. This is a pattern I've observed from other players' reports as well: crashes starting around 1280, which is the date of the Turkish spawn.
All of these games are on 600 AD btw. I find that older civs tech slower now on 600 AD starts due to lack of overpowered India and China.
