Treasure chest problem

Someone told me that you can do those once every 30 days. I've done it once since i installed NF and cant seem to get anything out of them anymore. I've tried to wait 30 days between treasure runs (33 days to be exact), but nothing seem to work. Is this a bug or im doing something wrong ?

It's guildwars being weird.
I've opened all chests about 4 times on my ele, while I'm still waiting for them to be available a second time for my warrior.

There is no exact formula of how long you need to wait until the treasures reset.
It's all based on guesses and observations.

I think that atleast One of your characters need to finish Nighfall in the End mission in order to get them to refill every month, not sure though. Something i heard

Otherwise they should just refill every month (30-xx days)

EDIT: From Wiki: "All treasure resets exactly one month after finishing the final mission for the first time on that character and opening the chest for the first time, if the chest has been opened before beating the final mission a one month wait is still required."

So i guess it should work for you now.

That's the real answer. Even the info from wiki is based on guesses and observations.

I've beaten the end boss (The all Mighty Abadon the Wussy) about 3 months ago.

So i guess the chest gets reset between 30 to 249,463,590 days.

tried one today and got an empty one. I'll wait another 30+day and give it another go.

thx all.

If you open them early, they reset.

try doing different zoning techniques to see if that works

You mean early in the morning ?

Not sure if that is sarcasm or not.

If you open them before you are supposed to, the timer reset. So if you wait 29 days and it will reset at day 30, and try to open it, it will add another 30 days to the timer.

Yea i figured that out the hard way . I also wouldn't suggest just meeting the deadline, try to go 2-3 months instead. Just to be safe and that the quality of the weapons will increase.

I 'll settle for the beginning of May for my next attempt.

Thank you all for your advices and help.
