I have to agree with Letrange:
This is an image, er, 2 days after I started a 96 hour job and I DID not start this this morning!. On a planet I regularly start other extractors on. And it has only 9 hours into the job. Its bugging me, mainly as I need to switch the job to a 5 hour one, as I have since Saturday.
Infinite monkeys, thanks CCP. :)
But seriously someone could abuse this - I can't replicate it yet, only thing for sure is I alter other extractors on same planet daily... but its not obvious HOW this is happening - but there is some logic wrong somewhere.
Just thought I'd add my voice to this based on my experience of PI so far...
