I had set up a simple Importer from a Tinkers smeltry casting table (with ingot cast) to a Crystal Chest. As soon as I added the card the game crashed.

@xSparky911x It looks like TCon is emitting a SidedInvWrapper with either a null inventory or side, which causes the game to crash.
Could you report it to their issue tracker as well? There's not much I can do to fix this from my end.

K will do although when hooking up Ender Conduit to the same side of the same casting table rather than the Integrated Tunnels pipe all seems fine.

Has been fixed on TCon's end.
