So I'm having some issues with Sky Factory 3.0.15 and was hoping someone here knew what was going on. I just downloaded it a couple days ago and got the point where I could automine/hammer and read up on getting an auto farm going. However when I went to try and get some rubber so I can make the plastic, I cannot find rubber in the list of items when I search. I did that @minefactoryreloaded search on the inventory screen and nothing shows up. I even got into creative mode and cannot find anything related to it. Am I doing something wrong to get that?

Other than that I'm having an issue where the game is now randomly crashing on me. I can play for a few second or an hour and out of nowhere it just stops and goes down on me. If I play vanilla it doesn't seem to do it, so I figure it's something to do with the mods.

If anyone can help with either of those issues it would be most appreciated.
