I had my destructive dupes only destroy my manual generator. Once it was broken, they'd go back to their tasks while remaining stressed. Not sure if this is intended.
More importantly, if it was left broken, other dupes becoming stressed wouldn't break anything and would stay on task.
I continued for a while after the bug was produced. I'm not sure if this will affect how useful the log file is.
Steps to Reproduce
Have a destructive dupe become stressed, wait for them to destroy the object, and leave it unrepaired. Destructive dupes will no longer destroy anything when stressed after that.
