Guild Wars 2

After some PvP games I did not accept the win chests. I started this weeks before the halloween event. Now after halloween I wanted to collect them all but there were just the trick and treat bags left from my wins during the halloweeen event left. All the chests have been deleted.

I know that Arenanet cant give lost items back but why should I accept the loss of my rightfully earned chests and much wasted time when it is the fault of Arenanet?

Why did you not collect them in time?

Because my inventory was full. I didnt hurry because normally they were saved until you accept them.

I don’t really get your issue.
You said you only received ToT bags, and this is what you are supposed to received during Halloween. Regular win chests were not available during Halloween.

You know the little cups that appear whem you win a tournament? In there are a win chest and some rank points. I had many of them BEFORE halloween. Due to the event patch my cups were deleted and so were my win chests.
