A few problems with cubing

So I logged on with 60k mp and decided to start cubing some random stuff. I bought 35 Miracle Cubes+ 10 potential locks, and 10 Enlightening+1 PSoK. I start off trying to cube my Ele Stave 6 with an ECube...that doesn't work, so I just say forget it and start regular cubing. I take about 5-10 cubes to get it to Unique and another 2 or 3 to get 30% boss damage. I'm pretty content with boss damage (of course), so I potential lock it...but after I cube it again, it loses its potential and I still have the potential lock in my inv. The other 20+ cubes were spent trying to get 30% boss with no avail.

I decide to give Enlightenings another try, but they don't do anything on any item I'm wearing. I'm not exactly sure what I expect to happen but...umm...help?

I guess there's a bug with it.

E Cubes and Potential Locks dont work, Revolutionary cubes dont work either :c
