Not a bug bro! See this update for more info! http://forums.playredfox.com/index....enance-09-05-17-patch-109-111-complete.37877/
Mhm, my friend made +7 Kylin clothes, but he didn't like addition attribute. So at next refinement he did let to fail, but clothes didn't vanish, he could refine from +6 to +7 again. It was Kylin clothes too.
There's either chance it will drop or it will break. I think high level refinement (+9 above) will most likely to break than to drop.
I see, but than players can't be safe to refine or try change addition stats at +7, while there is no guarantee to refinement lvl drop or cloth break.
