Just here to confirm that this TB isn't in the "All Aboard!!" (GC8Q2FW) cache. It looks like it's been a month or more since it's been gone.
You may want to go to the TB's page and "Mark Item Missing" so it doesn't show up as still in the cache. The cache has a high visit rate to drop and pick up TBs.
Cheers,
