Yes, I was so pissed off that I didn't read it properly :-) I checked yesterday night and the points were still reduced. Today Citi's website is under maintenance so tomorrow I'll check and claim my points if they are back to normal.  Such a bad luck, I was booking my ticket with Singapore...

This is unbelieveable! I have almost 200.000 citibank points and was about to use for a business ticket with Singapore Airlines. I'll call Citibank and cancel my card.
