Blue Essence Bug

My client crashed and I had to restart it. Instead of relogging in with my user and pass, it logged me back in with a pre-season update message and I noticed my blue essence increased by 50k. Sadly I didn't screenshot it at the time. But I restarted my client again being confused. I was able to put in my user and pass and was able to successfully log in. My blue essence amount returned back to my original amount.

I just wanted to report it to here cause the client gave me wierd errors.
