Today I got this problem where I cannot open the Enormous Mistwrought Chest at the end of the boarderlands jumping puzzle. I tried it on 4 of my characters and only the first one can open the chest. The chest appear to be shut and I got the press F to open prompt, but pressing F does nothing.
PS: WvW just rotated and this is the first time I did the jumping puzzle on that particular boarderlands, so this is not an issue of reset timer.
