FYI, Same issue with Tanning. furs are fully good-to-go, completed timer but not processed.
However, with tanning, if you put four rabbits furs in before, 3 will be ready to go bug, with 1 processed.
If you put another glob of tanning fluid in, it instantly completes. Try doing the same with your ore problems, light it up.
Looks like you just need to put a -1 second on your processing timers, Jorb.
