Is there a way to get profile pictures and skins from past events?

Hello, I really liked some México skins and profile pictures but sadly I couldn’t get them all from the past event because I went on vacation those days. When I returned I found the event was already off and I couldn’t complete all challenges to unlock items.

Is there a way to get them?

I don’t think so, once the event is over I think they get locked. Unless the devs decide to unlock them again sometime in the future

Currently there’s no way unless the devs will make an event that unlocks the past rewards like AoE2DE did.
