Yes I know but think it positive. It will take more time to grind the money for the mobspawner than start all over again and you already know what to expect form the quests so it will go even faster. Also relog and the bug gets fixed I think. Somebody had the same problem as you and he just relogged his minecraft.
Oh, you're right. It seems to island disappear after I relog to Minecraft. It is not a perfect solution, but it is ok.
Lawnti and Nxrlly thank you for your time and help.
