I was killed by a warp glitch, and lost some smoothstone, about 4 stacks worth. It's a pretty minor loss, but I'm running low on coal so I'd still like a refund, if I'm allowed :\ I don't really mind when you get to this.

Out of interest, which warp and what happened?

Happy, warps can still kill you. If you start to suffocate, relog before you hit the void.
