Subagent was interrupted due to the error “We are experiencing high load on the Grok 4.6 model; please try another one or Auto,” and after this interruption, it remained in a state where it could not be opened.
If the main Agent hadn’t been instructed by me to git stage between Subagent calls, this could have ruined several hours of coordinated agent work and I wouldn’t have been able to find out exactly what work the subagent had managed to complete and where he had left off.

Yes, I got an error message with a Resume button, but it disappeared because I tried to open the Subagent before clicking Resume.
