Blood Magic freezes during postinitialization.

No messages are printed to the log and the Forge anvil animation continues, but the loading screen remains stuck at "PostInitialization - Blood Magic: Alchemical Wizardry".

I'm using BloodMagic-1.9-2.0.0-33.jar and Forge 1.9-12.16.0.1865. I'd just updated my mods and deleted most of my config files, so if no one else is seeing this bug it may be because of either a mod interaction or config file generation. Check the log file for the list of mods ("[Client thread/DEBUG] [FML/]: Mod sorting data").

Can you reproduce with just Blood Magic?

Not with just Blood Magic, no. With the same mod set though I get the same result, stalling at the same point.

On second thought, 142 mods is a bit much... There were no memory errors in the log, but that's probably what killed it. If I remove Blood Magic, it gets to the menu, but the game lags out and eventually crashes with an OutOfMemory error when I enter a world. Blood Magic probably just pushed it over the edge a little sooner.

Yeah, that'd be it. Best to look at tweaking your java parameters, if you have enough physical RAM.

Correction: Not a memory thing.

This is caused by Compression, which you can find here: http://minecraft.curseforge.com/projects/compression

You can get the required library Origin here:

If you use just Compression-1.9-1.0.2.70.jar, Origin-1.9-9.0.3.371.jar and BloodMagic-1.9-2.0.0-33.jar you get the same behaviour.

I blacklisted the Compression mod's IRecipe in ba17fe1. After doing some testing, these are some of the loading statistics I found.

3200 compression recipes with just Blood Magic and vanilla. That's just... no.

Ok, so it isn't freezing up, the Compression Handler is just having to go through so much shit that it takes forever. So definitely not my fault.
