Do old locks still contain loot?

Ok spent 500 plat and got nothing on them...all it gave me was epic gears and I opened Holloween 2021 massive crates.
(this should have had better odds since it was a massive crate) even 1 item would have been reasonable.

do they actually have gear since it's connected to an old event....and usually an update takes all its stuff with it.

Yes, I'm unhappy with the results since I never opened outside of an event...this was my 1st time.
I think a better warning should be placed for old chests. (**warning opening a chest outside of an event won't drop loot** )

Thank you.

Lockeds do continue to have the same contents after an event, and you can always look at exactly what it can give before opening.

Closing.
