Seems to be a packet issue???

What you expected to happen:

For the crafting manager to work and to not get kicked out of the server while doing so. I just wanna put some patterns in it.

Steps to reproduce:

1. Click on crafting manager
2. Crash
   ...

Version:

• Minecraft: 1.12.2 (FTB Revelation, latest update)
• Forge: 14.23.5.2815
• Refined Storage: 1.6.12

Does this issue occur on a server? [yes/no]
