Guild Wars 2

2 days in a row my contacts list / guild chat has bugged out around 5pm.

Can no longer receive / send whispers, see party / guild chat, leave or join a party! Anyone else had this issue?

Each time its happened while doing TA explorable mode.

Make that 3 days in a row, 5pm again contacts now appear offline cant send / receive whispers see party / guild chat or join / leave partys again. Works again at 1 in the morning.

Any chance of a response from some at arenanet?
