Title. P2P bus and memory card work as intended in singleplayer, but with spongeforge 1.12.2-2838-7.1.9 this issue easily reproduced, whereby you attempt to use them through the same means, only in this environment it wipes the card.

I had the same issue with forge 2768 last year. Some versions of spongeforge don't produce this issue, but after attempting ten different versions this issue persists. I suspect the issue here lies with spongeforge but am filing the issue here as this mod is the only one causing problems.

Server output returns nothing when replicating the issue.

Environment
spongeforge 1.12.2-2838-7.1.9
openjdk1.8

• Minecraft Version: 1.12.2
• AE2 Version: 2rv6stable7
• Forge Version:2838

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

Should you be able to reproduce it without it and in a new environment and save, please update the issue accordingly and we will reopen it.
