Hey, thanks for the report. This is a known issue. After reverting to a previous checkpoint, the editor state can get out of sync, so @ mentions stop working.
Related thread: Reverting changes does not reset the context
The team is aware. For now, here are a couple workarounds:
- Instead of revert + re-prompt in the same chat, start a new chat with
Ctrl+Nand send your request again with the right context. - Commit with Git before experimenting, so you can easily get back to the state you want.
I’ve shared this with the team. Let me know if you have any questions.
