Issue Description:

Custom Pack loads okay (check mod list in log file), but on world boot that previously worked with EnderIO, the server side shuts down.

What happens:

Forge/EnderIO error says fluid isn't registered, checked the configs and it seems to be that vapor one.

What you expected to happen:

World boots okay with Ex Nihilo: Creatio and BetterQuesting freshly added.

Steps to reproduce:

1.Load up modpack (ask if you want download, not public available yet)
2.Load Up world previously created
3.Wait + check log if forge/ world worked
...

Affected Versions (Do not use "latest"):

• EnderIO: 5.0.20
• EnderCore:0.5.18
• Minecraft: 1.12.2
• Forge:14.23.2.2653-2654

Attempted deleting the configs for PE in which I tried to add EMC to infinity powder, got into the world. Thanks for the stack trace help. Also one question:
HOW DO YOU FOLLOW THIS CODE REPO?

Verry carefuly 😉

lol

Code organization; trying to learn how they programmed this. Kinda a java/modding newbie

Like what do you mean

The error causing your server crash is this:

Which seems to be a bug in ProjectE, not EnderIO. The error following that about fluids is likely related to the now errored game state. If you still get this error without a stacktrace blaming another mod beforehand, we can reopen this issue.
