A friend had blacksmithing leveled up to 93. And a few days ago ... deleted it by mistake.

(He says that due to a lag he misclicked, but I guess it's not that important now...)
Anyway, our support first replied that they needed to check if he did not get advantage by doing what he did. Then they sent something that is not very clear but may mean that they don't really know how to do this...
Have you ever had such a situation? If so - have you managed to get your crafting skill restored by support? Is it at all technically possible?
