Event stuff

So…. event stuff from earlier events. I had a 1,5 year break from gaming because of mental health issues… is it possible to get event or event items afterwards? I bought the pack life and death. But could not do the reaper event.

When the cozy celebration event was going on I was not even home (was on the opposite side of the country to get help) and had no computer to log in to claim the items or had someone that could do them for me. Is there a way to get the event or items after? Would be fun to do the event to like in scenario. And get the with reward there. I kinda feel left out on this….

i don’t use mods or cc, first don’t know how it works. Second I don’t want to lose my saves to crashes.
