Why did they do this!?

Sad

Hey guys :( i can't believe what just happened! I finished the story and uploaded the final chapters (this story) and started the sequel and published it. I woke up late last night 4 am to be exact and checked up on it and the sequel and all the new chapters apart from chapter nine were gone! I thought it was because I was really tired I was seeing things. I've just woken up again, checked up on it and the sequel is there but all the chapters over chapter nine are gone!!
