Add a set amount of gralats to the server, and never, never add any more. Give each job a certain amount of gralat, a portion of which is given to people who bring them gems, apples, whatever, and the jobs gain back money only when people buy the jobs' respective products (like bread from the bakery). You might have to add some new items (jewelry from the mining, for example) and give food some more uses, but it would work. A server reset would still be needed, however.
