Plugin creates massive lag because it creates items even while the rest of the chunk is unloaded; Meaning on chunk load, not only does the client crash because of the sheer amount of entities, but the entire server hanged (and subsequently crashed).
A responce from a support agent was:
"You have like a million items somewhere in your world"
It isn't laggy first up, second up you never contacted me. Who is this so-called agent if you really talked to him? We don't even have a support agent. This plugin may cause lag if you haven't properly set up. For any users: support is in the discord, not in your imaginary dreams about support. And to answer the actual part: Yes it spawns items. You can limit how many are spawned. How would it work then? You can use a lag cleaner to fix this issue. This is how the plugin is engineered. If you would have come in to the discord to ask for help, we would have helped you gladly.
