Summary0011907: Game freezes with 100% CPU usage
DescriptionThe game stops taking all input commands (but weirdly, the music keeps playing). No errors reported, I just have to force quit and lose all progress up until the last save. Once I start up the game again, it doesn't take long until the same thing happens again. This has happened to every fortress I've played. Occurs with and without dfhack, no other mods/augments.
Steps To ReproduceIt seems completely random; I don't think there was any common event that triggered the freeze, but it happens inevitably with every fortress. Seems to be the same issue as reported in issue ID 10619 and 10615 but on macOS instead of Linux.

Does this a happen on any save or a specific one? Not much can be done to track it down with out a save that reproduces the behavior.

Adding a # before an issue id creates a link - 0010615 (10619 is linked that one).

What processor are you using (Intel/ARM)?

We would need a save from shortly before the issue occurs, if it is reproducible from that state.

I'm using an ARM processor (Apple M1 Pro). It happens on every save I've played; here's the most recent one: [^]

About how long with that save does it take before the hang occurs?

I had seasonal save activated so it should occur within a season

I ran it for 4 in-game months (edit: up to 6 now) and wasn't able to reproduce, unfortunately (Linux 0.47.05). I'm a bit suspicious that running on ARM/Rosetta could play a role here.

In the future, it's most helpful to have a save that reproduces the issue in a small amount of in-game time (a few days to a week), or less if possible. I realize that's hard to accomplish if you don't know when the issue will occur, so frequent autosaves (if using DFHack or another tool) could be helpful there.

I have the same issue, Apple M1 Max. My current savegame crashes very soon. I suspect it has something to do with the dwarven output caravan arriving, but I'm not sure. Also, the game has frozen on random occasions before. If it can't be reproduced on Linux, it could indeed be a Rosetta issue.

Here is the game: [^]

Update: here is the crash log after I force quit the game due to a freeze. It's very long, but maybe it helps. It was too large to get it into a pastebin, but I uploaded it as a textfile (might expire): [^]
