That's odd. I've never had any trouble smelting either one I wish.
There are 2 ways I know of to choose it. First is to drag a stack of it with your cursor and drop it on the box.
The other way is to right-click the stack. (you can empty the box on the table by right clicking the asherite that autofills first).
Do either of these ways work for you?
(I did a bunch of smelting both of them yesterday as I just reached T1. It was working like this then)
So when i first started smelting, the only thing that would show was my Asherite ore. I'd smelt that until I couldn't smelt any longer, and then my Caspilirite would show up, and I'd smelt that.
But I recently noticed that when i'm finished smelting Ash, my Caspilirite wasn't showing up, and I couldn't get it to show up to smelt. after some tinkering back and forth, I figured it out. As long as you have some Ash in your bags, the Casp doesn't show up. I had to deposit the 2 or I had (since it takes 3 ore to smelt) in order to get my Casp to show up on the smelt menu.https://seforums.pantheonmmo.com/content/forums/topic/16183/can-t-smelt-caspilirite/view/post_id/288691 basketball stars
This needs to be corrected. The best solution is to just have everything that I can currently smelt show up on the list, period. Even if I don't have enough to smelt, it should be there, instead of just showing one at a time and forcing people to run back and forth between the bank and the forge so they can get an ore to show up.
That is quite upsetting! I agree that everything would go much more smoothly if we had the full inventory of ores that could be smelted, and it's fantastic that you found out the workaround. If you're aiming for efficiency, there's no need for so much back and forth. Hopefully, the devs will consider your feedback!
You can also just right click your ore slot in the crafting window to clear it and then right click the Caspilirite ore or any other ore in your inventory to then place it in the crafting slot. Until the crafting UI gets updated and what not, that is how I have been going between ores when they don't auto populate.
