Hi all!
Brian here!
With our previous hot fix update, we've unfortunately broke other things causing Smelter to be unplayable once you reach Guumbor. I know this has been frustrating for you all ><
We've tracked down the issue and are working on a fix as I write this post.
Really sorry for the inconvenience but we should have a fix very soon!
Please just hang tight while we get things back to the way they're supposed to be!
