Guild Wars 2

I beat W1 Zone 1 and Zone 2 in tribulation and received the King Toad pieces from the chest. When I beat King Toad in Zone 3 the chest appears and is already opened and cannot be looted, and nothing appears in my inventory. It just started happening after the patch today and I have tried killing him 3 times and I cannot get the loot. I tried restarting the client and it didn’t work.

Do you have finished zone 3 already today?
(Probably you hav started it yesterday before the daily reset but finished it afterwards)

Thanks. I did not know it did that. I must have finished z1 and z2 right before the daily reset and then completed z3. Bad luck.
