Lost Spell cast

So today I was praticing protego and went from Accomplished to adept. and after I was done, I logged out of the server. 

now I returned to see that its still Accomplished so I lost 700-1000 cast of protego that I worked hard for D:

I hope that you are able to help me out :i 

@crystalmare this is the 2nd report of lost stuff.  This is your problem

This is probably a bug that got introduced in crystal's latest version of core.  We will resolve it soon.  We will give you the cast data back when it is resolved.

@Crystal Bell

Thanks alot! will it still be fine if I keep pratice it to adept again so when I get my cast it will turn in to expert? so I can still train my protego
