Users could dupe diamonds. I fixed that.

Insert rate was 3750 and eject rate was 1000. 

You could eject a sheet from a protolathe and get 3750 cm worth, but only 1000 cm worth was taken out of the machine.
Repeat this and you can turn 1 sheet into 50 in no time. So BUGFIXED IT. 

Credit to Midaychi for finding this bug.
