Guild Wars 2

I was just wondering whether somebody could help me out here

When I am doing Guild Missions with my Guild it doesn’t show up in my Guild tab
For example I can’t see a list of locations when doing Guild Trek

Is this purely because my home server is not the guild’s home server or something else
If I find out the problem I can fix it

Thanks for any suggestions

It is because you are guesting on a different server indeed. A guild exists across servers, but the upgrades are per server. So on your homeserver your guild cant do guildmissions and they are not unlocked. this doesnt mean you cant participate when guesting, but indeed for the guildtrek it is somewhat difficult.
