What is with these errors?!

[-Logan]

I was versing the dragon on blue burst in hard mode heat sword when d/c occured. I thought someone joined my game. Now I cant even go on BB for some strange error. Last time I guess was an update where everyone was d/ced. What is going on?!

Was the error a Data Locked error?

If so, you were probably in the wrong place at the wrong time when hackers/dupers/whatever decided to crash the block you were in, d/cing you and everyone else in the block. That causes your data to lock for about 5-10 minutes, preventing you from getting in-game until said time is up and everything sorts itself out.
