I started to play in 2018, and I haven't been online since I retired at the end of 2019. Until I returned in 2023, I found that the blue flame skull in my backpack and my flash master weasel were lost. I haven't been on the number during the retreat period, and I don't know exactly when it was lost. I don't know who to ask for help, and I can't find any records. Is there any way to find the lost items?
