I got a chance to try out a clouded quartz silver ring, and when I right clicked it, it let me charge it, but there wasn't a color channeled to the crystal. It also didn't have an option to channel the crystal. Then also also (also x2 combo) it seems to have disappeared after unequipping it and trying to reequip it. Which is unfortunate.
I'd give a screenshot, but the ring is gone.
Pretty sure I picked up that ring and yeah I have the same bug. Can still equip the ring just fine but farwoods mysteries happen every day.
Sadly still unfixed but idk. Apparently already colored quartz *can* be channeled? Don't have a colored quartz on a ring tho.
Edit less then a minute later: it vanished. I'm assuming this was because I tried to charge it and it didn't charge. It still had the charge option.
Fixed.
