The title explains it.
I first noticed this when it had happened at PixelVortex's shop.
I believe explosions need to be removed or something to be done to keep from Ghast destroying islands.
I will try to get photos of this happening again if I can.

 

Thanks you for the report, the reported ghast has been killed with fire and its soul seeped from its body.

 

Just like SB with creeper explosions disabled, Ghast explosions need to be disabled aswell :/

 

its called hell block for a reason the ghasts are supposed to blow stuff up Cyp said that in a post earlier. anyways ghasts can't break cobble so make a cobble ceiling.

 

It's not fair to players that struggle to get cobblestone or do not want that to be apart of their theme.
Also where does it say that ghast are allowed to blow up islands?

 

Thank you for the report. The following ghast has been killed a painful death.

Moving to Reports: Killed :t:

 

It's called Hellblock for a reason. It's suppose to be a challenge. The challenge makes it fun. It'd make your island out of netherbrick and in a box to make it ghast proof, that's what I did on the old hellblock before it was moved and I never had any more ghasts attack me after that.

 

Thanks for copying my message, its like a thing now...

 

This isn't a bug.
