Issue Description:

Milk duplication occurs when EnderIO is installed and a milk bucket is added to tanks from any mod besides EnderIO

What happens:

When a milk bucket is placed into a tank from a non-enderio mod, the tank gains milk without the bucket emptying.

What you expected to happen:

The bucket should empty, adding 1000mB of milk into the tank

Steps to reproduce:

1. Install EnderIO and any other mod that ads fluid tanks (eg: Mekanism, Tinker's, OpenBlocks)
2. Place milk bucket into non-enderio tank

Affected Versions:

• EnderIO: 1.10.2-3.1.183
• EnderCore: 1.10.2-0.4.1.66
• Minecraft: 1.10.2
• Forge: 1.10.2-12.18.3.2422

Milk’s easy to get anyway.

what he meant: use an enderio item conduit to get that bucket into the tank from ex. TConstruct

Just to clarify: When you use the vanilla milk bucket with a another mod's tank, you get another mod's milk liquid and keep the vanilla milk bucket?

If that's correct, I don't really know what's happening. Ender IO isn't involved there at all. For one, it does nothing with or to milk or the milk bucket, and it is not mess with other mod's block's or the milk bucket's right-click interaction.

Have you tried it with milks that were added by different mods? If not, I'd suspect that the mod that is adding the milk fluid may be registering its bucket interaction incorrectly.

Hmmm... I thought EnderIO was involved because EnderIO tanks were the only ones handling it properly. But if EnderIO doesn't touch it than I'm not sure what to think

@zack-emmert have you tried these other mod tanks / milk buckets in a world without EnderIO and EnderCore installed?
