Hi, I was starting to play your mod, and found this glitch (occurs when tried to craft a storage in the wrench gui). Here the crash log :
crash-2017-12-30_19.24.25-client.txt

By the way, may I suggest to update the video in the curse page. Seems to be pretty old, and I had hard time to figure out all the features (i.e.: the hammer works very different in the 1.12.x version)

Thanks in advance!

Looks like it is caused by an empty recipe. It will be fixed in the upcoming version. Thanks for reporting this issue.
And yes, tutorials will be there soon. I know that it's a bit difficult to figure out how everything is working at the moment.

Is fixed now.
