First, some background: I’ve been having crashes in the game when using a save from eb049ca in later versions. It crashes at least from 9a30e07 and forward, not sure about interim builds.
No matter the build I tried and what I did to the savegame (removing .map files to have the game recreate the maps, waiting for any raw pelts and tainted meat I may have left around to rot away) it kept crashing when moving around the map.
I finally gave up and made a new game, with a new character and a new world in 5d24962, which also crashes when moving further into a town. This happens even after all NPCs have been killed via debug menu.
The savegame can be found here; move northwest towards the grocery store and the game will crash just north past the gun shop. https://drive.google.com/file/d/0B3AL9f2YbVzhenNFdVozY3V5ajQ/view?usp=sharing
Here is another save that crashes in ca14431 and later, which seems like it could be related. Exit the shelter and go directly north and you’ll run into the crash. https://drive.google.com/file/d/0B3AL9f2YbVzhSUVsRTQ4MzBPQ2M/view?usp=sharing
Both saves use a simple mod for 75% speed zombies that you can find here. https://drive.google.com/file/d/0B3AL9f2YbVzhaGlpQVRHdXA1M28/view?usp=sharing
I’m using the builds from http://dev.narc.ro/cataclysm/jenkins-latest/Windows/Tiles/
eb049ca did not exhibit any of these issues, to my knowledge. I had a developer friend take a look at it, and his fresh (5d24962 and later) Linux curses builds of the game also crash at the same points the Jenkins Windows builds do, with the same savegames.
