I Joined skyblock today and i haven't went on for a long time and when i joined i saw i someone grieved and i was staving so i tried to open my chest but it wasn't opening and i couldn't break or place blocks, now i thought it was doing that because i changed my name from bugnug123 to DerpyPotato_ so i made a new island and i was able to place stuff anyway i jumped of my island and i went into the void but i wasn't dyeing and i tried to suffocate, drown, swim in lava, hunger, poison and fall but i didn't even lose a half a heart. Can you please fix this because mobs won't attack me and i cant use levers and to do stuff like opening chest please help me cause i don't want to cheat

 

Well, island protection was enabled with the latest update. The server still DOES NOT support name changes. The griefing must have been done before the update though as because it was only a couple of days since the update came.

The second issue with the "invulneralbility" I have no clue about. The new update is very buggy and you might have a rare case of it. I cannot explain that.

All you need to do is be patient with the server. It will be fixed sooner, if not later.

 

The island protection still has quite a few bugs that they're trying to fix asap.
