Transmutation Tablet Woes

[mobilephone2003]

Hey guys,

We have an issue with these tablets, where players enjoy them but some are using them to dupe the tablets themselves (and sell at a high price).

Process goes:

• Place tablet inside tablet to learn recipe
  
• Put a diamond in to transmute
  
• ???
  
• Profit of 2 stacks of tablets
  

Is there any way to limit these transmutation tablets so this sort of thing can't be done? Getting rid of them has caused an uproar and some are saying it's killing the fun.

Banning the individuals doing it is one option, and i understand it is "expensive" to do but as the game progresses these things will get less expensive

Any suggestions welcome!
