Guild Wars 2

As long as the guild exists on that server you should… try guesting there and seeing if it works.

Guesting doesnt work I believe, but you could ask a friend to join your guild and pick up the items for you.

Guesting will not help you. You either must change servers back, or entrust someone who still calls that server home to send you the items from your Guild bank. The items will only be available to that server’s residents. Good luck.

^^ This. Trust me it won’t work. I did the same thing but by mistake. I left my server during what I thought was guesting. Too quick on accepting without reading. I planned to transfer but not before emptying my guild bank.
Guesting won’t help at all. The way I got my stuff back was by adding a trusted friend – that was still on the old server- to my personal guild and then giving them permissions. They had to wait 3 days ( hope I remember the time span correctly) before taking out all my items and mailing them to me.
Good luck and I hope you have a friend to help you out.

upgrades are not lost. they stay on the server you left. GW2 has a weird system where the guild influence and upgrades are not accessible to members across servers.

if you transfer from a server, you have to rebuild all the upgrades on the new server. if you want the previous full upgrades on a server, you have to re-transfer to that server with that upgrades.

hopefully some times in the near future ANET will implement a system where guild upgrades are accessible across servers.
