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):

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