Items dropped by a dead entity on a hopper continue to be visible

[baldo3000]

Describe the bug
Items dropped by a dead entity on a hopper continue to be visible after being collected by it. However that's only a visual glitch, you cannot collect them. Those fake dropped items disappear if you exit and then reenter the world.

To Reproduce
Steps to reproduce the behavior:

1. Place hoppers
2. Let mobs die on top of it (tested with lava in farms)

Expected behavior
Once collected by an hopper, the item should disappear from being visible

Runtime info (please complete the following information):

• OS: Oracle Linux 9
• Minecraft version: 1.20.6
• Mod version: 0.1.0 alpha 5.123

Checklist

• I am using the official version of the mod.
• I tried the latest development version but the issue persists.
• I searched for similar open issues and could not find an existing bug report on this.

Additional context
Removing "raknet;" from the server ip address fixed this issue, making me think it's somehow related to this mod

Try reproduce with raknetify as the only mod.

can confirm on a server with just raknetify 5.131.

happens relatively consistently when destroying a filled container in creative while close to unlocked hoppers
sometimes just the creative player itself is enough.

said "ghost" entities remain until relog.

i'd assume it's missing/loosing some deletion packets. maybe the delete packed arrives before the relative spawn one?

Try this version:

Try this version: https://modrinth.com/plugin/raknetify/version/0.1.0+alpha.5.137

this version seems to have fixed the entities not being deleted.

but now the opposite issue appeared where item entities sometimes do not spawn client-side while you can still pick them up and other players can see them.

EDIT: fixed typo ( now -> not )

It is normal for item to spawn on the client and you can pick them up. Did you mean it do not spawn client-side?

[mattymatty97]

no i mean they do not spawn on the client while they are there on server and for other ( non Raknetify ) players

[ishland]

Are the items visible for other Raknetify players?

[mattymatty97]

i haven't been able to test that yet. i'm the only one using Raknetify in my server and i do not have a second account to check
