setup:

goliath with queen beam, holding 1x bhm2 w/ 3xhd.

what i did:

create group, undock from goliath.. target/mine roid with bhm2.. command goliath to mine same roid.. when bhm2 is full, jettison, command goliath to gather.. move to new (large) roid.. begin mining, command goliath to mine..

..now goliath will continue to mine even though capacity is over/full, until you stop it or move to the next roid.

ive managed to put 1600+ cu into my ship (including my bhm2), could possibly go higher.

actually, it seems the circumstances were wrong.

its not mining over capacity at all.. after it picks up my first load of 160 and resumes mining.. then i dock with the ship my ore onboard the goliath is multiplied.

Thanks for the report. We fixed this late last night.
