About a second after booting to the title screen, the game crashes (crash log is linked below)
My theory is that another mod, 'menu mobs' causes a conflict with EnderStorage as on removing 'menu mobs' the problem does not occur

I don't know much about modding, I am just a user, so I have no idea what is causing your problem. It's not the end of the world for me because i didn't really need that other mod; i just wanted to let you guys know that there is an issue afoot!

Can i have a link to this mod causing the crash, the only way this could happen is if the world load event is not fired on the client..

Im getting this crash as well Log @ http://pastebin.com/N7Psu8Em very very minor diff between my crash report and the other .. but deff the same issue

The difference with the error that I came across and the one that the report it linked to is that the title screen had only just loaded when it crashed; I hadn't got around to making a world which is where the other error apears to have occured...

But yes, I thought that menumobs was the issue... out of interest, do you think it is something you can fix on your end or should I send the same bug report to the other mod's creator?

I would hold of on reporting it to him as Morph has already done that, tomorrow ill investigate why this is happening in more depth and see if i can fix it for the other mod.

Sounds good... glad I could help

I'm defining mc.thePlayer to load a fake nonticking world. EnderStorage crashes at clientState.update() because onWorldLoad never has been called. The null check above it checks if mc().getConnection() != null wich will return true because mc.thePlayer.connection isn't null.
I propose to check in ClientUtils.inWorld() if mc().theworld != null instead of the connection if this wasn't done on purpose.

This is the one that I think caused it

I have this mod in my pack, have disabled it and testing now.... Ok after disabling the mod, i can confirm that menmobs is indeed the issue

This has now been fixed

This hasn't been fixed right?

I was going off what Morph said.

Yes it is fixed.

So is this fixed now?

They must be doing some weird things to events, I'll look in to it later on today when I'm at my computer.

Yeah, that was my guess... I just thought it would be best to let you know to avoid future issues e.t.c. glad I could help
