This still exists in v1.2.27
@nexxeln I think it's critical as it keeps crashing the client often when trying to access the subagents tasks. Are you looking into this?

All the time... I can't live like this. Seeking alternatives.

@adamdotdevin do you know if there is any on-going effort to fix this ?
