Guild Wars 2

These issues are really annoying and I got few

1)It loads slowly
Not very slow but it still very annoying just to wait for the menu to load and for each option I pick it just take more than a minute to load

2)Sometimes when I attempt to buy something it just close the buy menu but it buying the same item without telling me
When this happens I just don’t know if it bought the same item or not so I’m trying to buy it again.

I go to the NPC to get my items and I notice I bought the same item twice or more in some cases and then I lose money
when you try to sell it for the same price you just can’t because you sell it for half of you spend.

Sometimes I if it happens I just wait more than 10 minutes and then I check again if it bought it but its really annoying

I must indicate that my ping and fps are not changing while this menu is open
I can play freely while its load and I notice that some people complained about a drop of FPS and the ping increaseing
I do not experince these issues but what I said above I do and I wonder if there’s a fix for it.

Thanks for the help:)
