Crash issue :

Here is the log : http://pastebin.com/8mQ1jvhV

Please provide more information. Is this producible in single player or is it a multiplayer issue?

What is "transfering an item"? I'm not familiar with Refined Storage, so please show your setup and how you're using it. Is a crash always reproducible?

Hi, sorry about the delay. it's a single player world. Actually Refined Storage is an AEish system, there is a storage controller linked to a drawer controller.

This is how I'm using the API, I don't think I'm doing something wrong, but it's possible:

i've talk about this issue to the dev here http://minecraft.curseforge.com/projects/refined-storage?gameCategorySlug=mc-mods&projectID=243076#c201

Maybe you should talk to him ? I'm sadly not a dev, so i'm unable to help you on this point. Anyway keep going on your very helpfull mod !

The problem is probably not related to the integration code in Refined Storage. It's a client rendering error, and one that suggests data may not have synced with the client, though I can't figure out how that particular line is able to crash.

@Moustik2002 please include a screenshot of your setup that is causing the crash, and tell me how often it's crashing or how you interact with your setup to cause it to crash. I played around with some of the RS blocks but I'm not seeing problems.

I think this is definitively fixed in the latest version.
