The attached adventure mode savegame reproducibly crashes after a very short time (about 22 time-steps). The world was generated using the Linux version of the game, but the same crash happens if the savegame is loaded using the Windows version under WINE. Since it happens whenever time passes (just moving around, travel screen, sleeping,...) it maybe could be some world event that causes the issue.
