Summary0001513: CF Backpack doesn't drain and is exploitable
DescriptionThe CF Backpack, when filled and used to the point it gets to about 800mB or less, when used via the CF sprayer on more blocks than the backpack has CF for, the client will be kicked with a 'internal server error' but on return will find that it sprayed correctly but has not drained either the backpack or sprayer, essentially duplicating CF.
Additional Informationoccurs on SMP
TagsNo tags attached.

oh the backpack works correctly when the CF sprayer is empty, but if the CF sprayer has any amount in it the bug occurs.
