When choosing to train a genjutsu at my home town, the drop down box has a blank line, like the name was left blank. Since it was the only genjutsu i was able to choose when i visited the temple i figured it was a bug and the name wasn't being loaded properly. However when i chose the blank name and chose train it tells me
You chose a jutsu that doesnt exist or isnt yours.
So this is a bug obviously since i went to the temple, learned the jutsu and get a blank name back home.
