Hey, latest forge version, testing with only Immersive, having this issue when client is starting

The game crashed whilst initializing game
Error: java.lang.ClassCastException: blusunrize.immersiveengineering.common.util.IEItemFluidHandler cannot be cast to net.minecraftforge.items.IItemHandler

Duplicate of #2934. Downgrade Forge by a few versions. This is a Forge issue, I'm working on it right now.
