Everyone's excited for a big tree drop. But oh, you go to check it, and the entire tree is filled with scars, free explore decor, and other items no one is picking up. Shame.

I think it would be beneficial that once the tree fills up more, items disappear after 10-15 minutes (or something around that time). Each individual item would have its own cooldown instead of just a random refresh every fifteen minutes (in fear of clearing out a good item that drops just as it refreshes). Maybe items with higher value could have a longer refresh cooldown?

edit: maybe longer refresh time, like 24-48 hrs?

Give some better ideas in the responses?
