Guild Wars 2

I just finished Z-1 and Z-2 Tribulation mode, and I am assuming I must have “returned to hub” before the post-boss timer hit 0. Now because of that, I am unable to select Z-3! I posted a bug report with a screenshot, hopefully this can get resolved. Any advice, or similar occurrences?

If you really want to do z3: redo z2. It’s the only way around it.
Stay near chest at the end, don’t go to hub before you’re suposed to.

They probably even can’t “just open” it for you.

I also have this issue and it has nothing to do with chest timer. I have completed zone 2 tribulation mode in world 1 and even entered zone 3 but then decided to spend my 500 baubles and i returned to hub. Few minutes later i wanted to try zone 3 and then i saw that i have only zone 1 and zone 2 !!!!!!! WTF arena come ON I dont want to repeat whole zone 2 just to be able to play in zone 3 this is just ridiculous.
