As described here: https://github.com/AddstarMC/Prism-Bukkit/pull/297

Prism uses the WorldLoadEvent to register worlds and as a multiverse user myself I've never had any issues but if there's any further details, this is where we'll track it.

Here, the PrismPlayer is actually always loaded from cache, I'm not sure why we put it here. It just creates a lots spam, blocking us to check other useful debug messages.

Describe the bug Lingering potions when thrown and if the mob gets killed, it only logs who killed it but the name shown is "area effect cloud" which infact is normal but doesn't tell who thrown it to cause the entity to be killed. So it means we can't know who did that.

To Reproduce Steps to reproduce the behavior:

• Have Prism installed on the server and spawn a random mob enclosed in a room.
• Give you a lingering potion (Instant Damage) then throw at the floor where the mob is.
• Wait until it dies
• Inspect it with /pr i or /pr lookup, you'll notice it will only say "area effect cloud killed (entity)" but nothing else will tell who thrown it for this cause.

Expected behavior A clear and concise description of what you expected to happen.

Prism should tell us who thrown it and who killed it (infact its area effect cloud), logging both actions just in case.

Screenshots

• If the current behavior is a bug, please provide the steps to reproduce and if possible a minimal demo of the problem** via

I used an alt to attempt killing the said entity (Pig), even checking at my alt's position nothing tells me who thrown it. Server (please complete the following information):

• Prism Version: 3.3.0
• Server Type: [Paper]
• Server Version: 1.18.2

Additional context Add any other context about the problem here.

Better ways to remove the Item Entity when rollback, and many fixes and improvements

Tested on 18 servers(statistics from bStats). Works fine.

IMPORTANT: These actions still duplicately rollback or restore. Merge this PR https://github.com/prism/PrismRefracted/pull/27 then we can fix it.
