Plan Mode- Build Bottom stuck on 'Building...'

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

The creation of a plan proved very useful and the way it executes the plan is better than an agent. but sometimes I face an issue where it shows building no matter what I do. The first time I encountered it, I get a small version update and it was fixed in that chat. now I am stuck and have to let the agent do the plan due to lack of updates. I tried building another plan on top but I just can’t accept the plan! plan mode does work in other chats though.

Steps to Reproduce

create a few plans and execute them in the same chat, stop one before it finishes or something I am not sure how but it happened a couple of times and I don’t see anyone posting it

PLAN mode doesn’t have this

Does this stop you from using Cursor

No - Cursor works, but with this issue

Hey, thanks for the report. We’re aware of an issue with Plan Mode when creating multiple plans in the same chat. This can cause the Build button to get stuck or disappear.

Workarounds:

  • Check if the Build button appears in the plan document itself (not just in the chat view) you may be able to run it from there
  • Start a new chat for the next plan execution
  • Reload the window Cmd/Ctrl+R
  • Check for errors in the Developer Tools console (Help > Toggle Developer Tools)

The team is already investigating Plan Mode issues with multiple plans in a single chat session. Let me know if these workarounds help.
