Hi there. 8/10 times if I buy something from guild store,i need to do relog for get mail with item,this bug since early access,dont you think its time to fix some bugs before u focusing on thinks like new maps...
Happens to me as well..I find that if I just hit a wayshrine and port somewhere else my mail will instantly pop. Not sure if this is intended, but wouldn't surprise me due to how everything else is handled in game.
