I've been experiencing this bug on and off. It usually only happens when I'm scalecrafting, but today, it's started doing it when I was smelting.
A few screenshots of this bug: http://imgur.com/a/KCLX8
Things to note:
- I am clicking on the correct machine; see the screenshots.
- I have the scalecraft/smelting buff applied (as appropriate for what I'm doing; smelting for making bars, scalecrafting for making dragonscales and deconstructing them)
- It does not seem to matter whether I'm using a tool claw or regular claw; it does what it wants regardless.
- Since I do most of my craft grinding outside of dralk, in that one event lair (http://i.imgur.com/dIwYiwu.png), that's where I've experienced it most - however, I've also seen it do it on the essence chamber on the Isle of Wisps.
I have tried:
- Clicking other machines or other bits and pieces around the lair, and then going back to the machine to see if it'll update. Sometimes this works, sometimes this doesn't.
- Closing the window, moving closer (or further) from the machine and then opening the window. No apparent effect.
- Just closing and opening the window repeatedly. This usually does not work. It doesn't matter whether I double click it, or I go through the long way and search the menus for the right item.
I have not tried:
- Logging off and on because I am grinding and I don't have time for that.
It usually resolves itself if I give it enough time, but I don't know for sure what causes it to start to work, or what causes it to stop working. I've returned recently, but this is not something I ever recall experiencing when I last played (however many years ago), so I am assuming this is a relatively new bug.
Weird companion bug: every machine is the right machine (this only popped up when I doubled clicked the machine by accident, and I think my last crafting project came up.)
