Additional context

Environment

• Minecraft Version: 1.12.2
• AE2 Version: appliedenergistics2-rv6-stable-6
• Forge Version:1.12.2-forge1.12.2-14.23.5.2810

Not 100% correct. Sponge does a lot of Things differently than a normal server, this is why it is not supported. If the issue can be replicated without, there still would be more informations required to help this case.

For now just a random guess, some plugin or config is messing with floating items on the ground.

We do not support anything like Sponge or Bukkit officially. Only a standard forge environment.

Should you be able to reproduce it without it, please update the issue accordingly and we will reopen it.

But,it just happen in the server,the forge version is 1.12.2-forge1.12.2-14.23.5.2810 .

Correct if I'm wrong, but Sponge is just a serverside modification, isn't it?
So you are just proving the point, that the issue is caused by sponge, since Singleplayer does not use Sponge and everything is working fine there
