A Claude Code User Reports Their Hooks Vanished After an Overnight Container Swap

A GitHub bug report, anthropics/claude-code issue 108252, filed November 8, 2026 and tagged as a bug with a repro, says a long-running Claude Code cloud session lost its user settings file when its container was replaced overnight. The reporter says ~/.claude/settings.json read {} afterwards, so the UserPromptSubmit and Stop hooks no longer ran.

The report says the session did display a notice that its container was replaced, but that no warning was shown to the user or the agent about the settings reset or the hooks stopping. It lists Claude Code 2.1.319 and macOS as the environment. It links to related reports of hooks that never fire in new sessions and of ~/.claude being silently reset on Windows, with the cause unknown.

This is a user's report, not a confirmed product-wide event. No reply from the maintainers appeared on the issue when we read it.
