Same issue here. Stopped while making changes. Only a new claude instance will work, so the scripts are broken now.

[KentaSUGAI]

Thank you. The issue is resolved.

The best way to handle this is to first run a /export that will export the current conversation so you don't lose any context. Then /clear to reset the context. Then prompt "@[name-of-context-file].txt continue from here", Example: "@2025-07-31-this-session-is-being-continued-from-a-previous-co.txt continue from here". After that Claude will have the same context as it did before the issue. Then continue as normal.
