Summary0013328: Game crashes a few minutes after a Giant, Ettin, or Titan shows up.
DescriptionThis specific Issue started happening on November 3rd 2025.
A giant, Ettin, or Titan will show up on the 11th of Malachite 190 and a few seconds to a few minutes later the game will crash.

I have had crashes in the past, which has pushed me to manually save more often, but this is the first time I’ve had a crash that doesn’t go away after one or a few reloads.

Vanilla Steam version.
World created after the dye update and before the Siege update.

Terminology correction: Data pasted in the Additional Information section came from errorlog.txt not a crashlog.
I have been informed that the game does not yet create crash logs on Linux.

I have also been told it may be possible to backtrace the crash using something called a debugger. If anyone can point me
 me to a walk through for doing this I would appreciate it so I can add the backtraced crash information to this case.

Turns out my save was corrupted. One of the calling cards of this particular corruption turned out to be a decrease in the number of files in the folders for game saves. I had a few saves from before the corruption event happened. I lost a few in-game years of progress but at least I didn't have to completely start over.
Thank you to the people in the Kitfox and DFHack discord who diagnosed the problem and helped me understand my situation.
