Cursor IDE
Describe the Bug
When subagents have been running for a while (sometimes with nested subagents), they often disappear from the chat pane, but they’re still running, because I can see files getting updated in the source control tab. In addition, I may have already opened the nested subagent to view progress in the main panel, but when the subagents disappear from chat pane, there is now no ability to navigate from the nested subagent panel back to the parent subagent panel when the nested subagent finishes. The only way to open the parent subagent panel is from the chat pane, where all of the subagents have disappeared. This usually happens for long-running subagent processes (sometimes the chat pane says “Taking longer than expected…”) - anyone else experience this? Is there another view to see active subagents/nested subagents? Is there any configuration or cursor setting that can address this issue?
Steps to Reproduce
Start a subagent process which spawns nested subagents which call external CLIs and runs for 30+ minutes. The cursor subagents and nested subagents disappear from chat pane so progress is no longer visible.
Expected Behavior
The subagents and nested subagent snapshot/summary/access button should continue to be visible in chat pane which opens the full subagent transcript/progress panel.
