Okay, I have a weird problem. I can't seem to improve some of my gear, because it won't show up in my gear when I go to improve it. It's only a few select items. I have tried on two different characters, and have the same problem. Doesn't matter if it's on the character or in the bank. Doesn't matter if it's locked or unlocked. One piece finally worked when I equipped it on the character. The other piece I am trying to do didn't. So, at the time, I had equipped 7 pieces of purple gear - 5 shacklebreaker, 2 slimecraw. I was trying to improve my slimecraw to legendary. After finally equipping both pieces of the monster set, one of the two showed up to improve; the other did not. Also, only 4 of the 5 shacklebreaker show up for possible improvement. What in the world!?!
