My points dropped for no reason; it's not midnight yet when it happened, 10 40 pm EST USA

I had over 1,000 points inside the green circle. Then I had a grammar question so I asked first before I forgot but when I went back to my lesson and practice I only had 420+/- points; it's not pass midnight yet. In the past if I had 2500 (the number just pull out of my head as an example) accumulative points but I worked past midnight. So the computer would give me the points up to midnight, say 2000, and credit the 500 for the next day. 

Another computer glitch?  

ADDENDUM: The lesson I was on was 6.9 Making a Complaint.  How appropriate :-)

This happens to me all the time with Japanese, so I can never get more than a six or seven day streak going because I wake up later on weekends. It's definitely not set to *my* 24 hour day. :(

May be they thought you were in Japan. I have relatives in Tokyo and that's why I know they are 14 hrs ahead, ie they are Thursday 6:32 am as I'm typing while I'm on EST in the USA.
