So, are loyalty boxes/their contents destroyable by site events like the Red Rreign? I'm extremely indecisive so I've been hoarding my boxes all these years and I've run out of Locked inventory slots. Since they can't be put into the vault or anything, I'm a bit hesitant burning stuff, in case it happens to hit the boxes or the totems...

Well, I'm not 100% sure, but I heard of boxes being zapped and stolen (when the event still existed) when they weren't locked, so I would think it's also possible that they are a risk to get destroyed by the Red Rreign. Maybe just use the ones that aren't locked?

I think that the Red Rreign burns items between rarity 1 and 99, so any special items should be safe.

To the best of my knowledge, since the Loyalty Boxes have to stay in the inventory or be used, they are protected by code or at least should be. If the Red Rreign takes one out then you should file a ticket.

Also, when I was burning wreathed red rreign items earlier (because I am working towards that Flameo skin), I received a message that basically amounted to me being lucky I didn't have any items in my inventory even though I have more wreathed red rreign in there... Therefore I think is right about the Red Rreign only recognizing items rarities 1 to 99.

...and this is why I think we should either get more lock spaces, or have LBs become vaultable -_-

I don't think the Rreign can burn them, but I'd open a ticket now (prior to potentially losing one) to confirm this information with staff before anything happens!

[edit] Whenever you get this sort of important question, don't hesitate in opening a ticket to ask c: Even if the information is around on the forums, they'll gladly help you out and you'll have official proof of that if you ever need it on the future!
