What happens:

What you expected to happen:

I can't connect to my server

Steps to reproduce:

1. Connect to a server with enderIO

Affected Versions (Do not use "latest"):

• EnderIO: 5.1.55
• EnderCore: 0.5.73
• Minecraft: 1.12.2
• Forge: 2860
• SpongeForge? no Mohist
• Optifine? np

You wont get support here because 1.12 is way too old but 1.12 waterfall seems to do strange stuff, when you check their github page but they also did not seem to fix those in the past
