Refined Storage 0.5.33 made some fairly significant changes and it's causing a crash with your mod. Refined Storage Addons version 0.3

Looks like refined storage broke its API, should be an easy update on our end. I’ll look at it as soon as I get a chance.

Gigabit already pushed a fix a few weeks ago, the current build should be release-ready.

Ah awesome, thanks. I’ll push that as soon as I’m at a PC.

Its on curse waiting for approval

Crash general. Its a compat issue because of the changes made to the crafting-system.

In single player it loads up, but soon you open up a world it crashes.

I swear I thought I tested that, but maybe I didn't. Anywho...I will edit the OP to reflect that. Thanks @accessdenied0

To be fair, in this world, I already have a Reborn-Storage Crafting-chamber setup (4x3x3 with 1 page) with some recipes in it, from last version of Refined Storage (1.5.32). It makes it a perfect test world for this change. Maybe it doesn't crash without any setup or recipes.

Makes sense actually :)

It is now live
