Might just be me, but did Anet just change the description of rewards from the black lion chests.
1 small change and you cant stack them anymore. Used to say Account Bound on Acquire. Now it says Account Bound. Kind of ridiculous as you cant stack the 2 different types. Don’t know if its a bug or what it is. But it is definitely annoying. It’s boosters, bank express, TP express and probably most of the other rewards.
Hopefully this changes again, so they can all be stacked.
