Description

We've update our Server from rv5-alpha-8 to Crash on rv5-stable-11. (in Modpack Modern Sykblock 3). If I start the Server with a new world everything is Ok. Only if I start the existing world the server will crash.

Environment

• Minecraft Version: 1.12.2
• AE2 Version: rv5-stable-11
• Forge Version: 14.23.4.2749
• Pack: Modern Skyblock 3
• Location: Server
• Crashlog: https://pastebin.com/gt9HPSjM

We've just started wit AE2. We have a little bit Autocrafting, Advanced Inscriber (automated), Wireless Crafting Teminals. Wired Crafting terminals on the whole Island.

This is actually a crash caused by yabba (more likely) or Astral Sorcery while attaching their itemstack caps.
