I think the server is lagging because the string from the duper isn’t getting picked up by the hopper. It could be that the hoppers are too slow or the chest is already full. If you guys are planning to make a custom item that produces string, maybe make it work like a chest that generates one stack of string every 32 seconds. Once the chest is full, it should stop producing more so the string doesn’t just stay on the ground, wait to despawn, and cause lag. That way, the string goes straight into the chest or even into a selected chest without piling up.
