Environment

• Minecraft Version:
• AE2 Version: appliedenergistics2-rv6-stable-6.jar
• Forge Version: 1.12.2 2838

Can you try again without sponge? (aka without the aaaaaaaaaaaaspongeforge-....jar)
This looks like a Spongeforge "optimization" issue, that causes non-deterministic stuff to happen

The following is based on my own research regarding this issue. For the moment I have great difficulty reproducing this at all, but:

Additionally compactmachines might be involved, has those are also loaded when their chunks are loaded and when a ME System is partially inside one of those, Sponge seems to do multithreading on separate dimensions causing conflicts within the ME System. Normal Forge does not multithread stuff like that.
If that player has part of his ME System in a Compact Machine, please ask him to get it out of there.
