I've just received the below message in my Town Mayor
QuoteThe Helios Tower on the island of XXXXXX has crumbled. Only the dusty ruins testify to the existence of this once magnificent structure. The settlements on this island no longer benefit from the tower's bonus.
I was under the impression that Helios Towers were supposed to be permanent and survive account deletion / graveyarding / transfer, becoming a permanent part of the world. Has that changed? I've read the previous thread on the subject (coincidentally [?] a year ago) and there was no resolution.
