If you guys could go ahead and restrict the use MBs while being on another world

I love that I can go to another server to buy things. Cause sometimes when I want something my server either doesn't have it or it's way to costly. So please keep the ability to buy things from other servers.

Then let sellers sell on those other servers or link all MBs up (per data center of course).

Otherwise get rid of being able to buy on other servers.
