A portion of my island suddenly disappeared, did I get griefed, also whoever Tabbymeaw is, he/she was around when it happened, and I don't have him as a coop. I need this resolved.

 

P.s. just now, I MSG Tabbymeaw and then they suddenly logged off now

 

You probably built further than the restricted area which is 100x100. If the player starts a new island or logs back on the part that is passed that line gets deleted.

 

Yes, I now know that. But I can't do much about it now.

 

Max island size is 49 from bedrock or 100x100. ?Usually people go 49 from bedrock as it equals 99x99 which is good for symmetrical buildings.

 

Actually due to short term memory loss, I griefed someone else island and forgot, then got banned, although I'm leaving this message, I might not come back to skyblock
