Well it has come to my attention that some Advanced Builder's cannot go into ADV map due to either there screen freezing or they disconnect without warning.
This problem may result into user of WOM client but some ADV's are cautious to get building in ADV map but cannot.
My suggestion to this issue:
. Zion creates a temporarily Map called AdvancedBuilder2 just for the time being until this problem has been resolved
Thanks
