Can't buy bonus skill 'idiom' in store
I earned three bonus skill slots yesterday then I found two skills in store. I figure out I really like 'idiom' but its cost is 30 lingots which exceeds my account so I decided to save up for it. However, when checked my goal earlier I only find that its price is gone and I can't buy it anymore. Does anybody know the reason? What can I do for it?
Probably it is temporarely. I have checked it and the bonu skills are on the right place for the languages wich have rhem.
I have no clue. It's still not available. Sad... There is no price at all. But thanks anyway.
