Guild Wars 2

I’m not sure if this is a bug or not, but today i switched servers with some guildies. However doing so my guild lost all the upgrades we ever had for it. Is this normal?

Guilds are tied to the servers they were created on. If you transfer servers, your Guild bank, and all influence, upgrades, etc. stay on the server it was created on. If you left items in your Guild bank, you will not be able to retrieve them by guesting. All influence will have to be earned again. All upgrades will have to be re-built. Though, if any guild members still reside on the original server, they can access the Guild bank and send items to you.

So, yes, this is normal.
