Crashes

[Dezz]

So, my game will crash every so often, but only when I try to craft stuff with the ME Crafting Terminal.

I believe it has something to do with SimplyJetbacks

Is there a specific item you are crafting when this happens?

Is there a specific item you are crafting when this happens?

No, it's generally whenever I hit the "clear" button on the ME.

It's happened before with a ton of items. Ironically, the only ones I can remember is when crafting ME Storage Cells

I suggest bringing it up with the dev of Simply Jetpacks.
