Both events are not far from now, so I have a small request for both of them - greatly reduce amount of event junk spawned in the world (both initially and as time goes by) since it increasingly negatively affects performance. It has been a great problem for both events, with world being littered with junk that most mobs drop. Worst of all is that junk is useless to the point that nobody stops by to pick it - there's so many varieties that take up different slots and they don't even burn.
I for sure am one of the people who avoid trading with pig king during hallowed nights due to all that junk he gives in addition to gold. I don't need it and nobody else does.
The junk includes Halloween Trinkets, Candies & Decorations from Hallowed nights and Winter foods + adornments (excluding festive lights) from Winter's feast.
I suggest making junk obtainable only on purpose instead of being spawned in the world or being extra drop from mobs. For example, make it a complex condition that is hard to fulfill by accident. Let's say, killing a mob within 4-tile radius of either Totally normal tree or Winter's feast tree would have a chance (from tiny to slight depending on decoration) to drop junk. Pig king would give candies only for Halloween trinkets and only at dusk. Remove adornments and winter foods from loot table of Winter's feast tree gifts.
