So last night I had 2,702 mush.
This Morning I still had the same amount.
I check on at the evening (Around12-1:00 p.m.)
And I only had 2,467 mush.
I didn't spend any, since I am doing a giveaway.
I don't know how this happened.
No one knows my password, and there wasn't anything suspicious messages. I did have some issues with someone about 2 weeks ago, but I don't think its related.

As you can see, I didn't spend anything yesterday or today.
