Issue Description:

Issue reported by 45gfg9 on the CurseForge page of my mod, ModernConverter.

The game crashes when the Energy IO tries to push ForgeEnergy into the ConduitBundle.

What happens:

A NullPointerException.

What you expected to happen:

That the conduit either takes the power or reports being full.

Steps to reproduce:

1. Place an Energy IO from ModernConv and give it power
2. Put it in export mode and attach an EnderIO conduit to it
3. Game crash

Affected Versions (Do not use "latest"):

• EnderIO: 5.0.26
• EnderCore: 0.5.30
• Minecraft: 1.12.2
• Forge: 14.23.4.2705
• ModernConverter: 2.1.1

Have you verified that it is not your own variable (proxy) which is null?

You are trying to push energy on the client. Do that on the server.

@tterag1098
getForgeEnergyProxy() is non-nullable, so that is unlikely.
@HenryLoenwind
That might be the case. I'll check once I get home.

Not just "might", the crash log says Thread: Client thread, so I'm quite sure you are ;)

And yes, returning true from hasCap() on the client-side is bad code we have in there to allow RS conduits to work.
