Well I used gems and my entire guild did and I know of many guilds already preparing to hit both GREE and I tunes for refunds if our stats go down again after you admit to a mistake on your part. I agree with the above you can not keep altering these games mid way through. If it was a free game fine it is not we are spending our money to again be stung for something that we have not done. You should let this play out. Test them out before release and save all the anger and hassle that you keep causing.
