Steps to Reproduce

1. Install Claude Code v2.0.73 on Windows

npm install -g @anthropic-ai/claude-code@2.0.73

1. Start Claude Code in any terminal (Git Bash, PowerShell, or VS Code Terminal)

claude

1. Trigger any output containing a numbered list. For example, if you have a CLAUDE.md with a numbered menu like:
2. New
3. Existing

Only "2. Existing" will be displayed. "1. New" is invisible.

1. Tables and formatted output may also appear garbled or collapsed.

1. To verify the fix, downgrade to v2.0.50:

npm uninstall -g @anthropic-ai/claude-code
npm install -g @anthropic-ai/claude-code@2.0.50
All list items will now display correctly.
