[twitter-dev] terrible! my statuses lose! from 3000+ to 84

[bang]

I began to use twitter one year ago. I have been posted statuses no
less than 3000, but today I found my statuses count become 84! Then I
go to twitter homepage to see my statuses, I can only see 84
statuses..... why does this happend? Can I have my missing statuses
again?
