One of the moderators/administrators already wrote (maybe on the facebook page) that there is a limited amount of t8 and t9 tiles that you win ... they keep replenishing them until you reach the amount won ... if your kingdom farms them fast then your kingdom will run out of them fast ... we have won tiles every fury event ... this time we were out at start of cvc but our cvc opponent still had tiles for quite awhile during the first day until they were out also.  We try to make sure all our tiles are farmed first two days so cvc opponents don't get to farm them for cvc ponts.
