I have to leave for 1-2 months as someone very close to me has died and I have many many formalities to take care of. Because of this I'm requesting a 1-2 month absence so my island is not reset.
Unfortunately, 59 days of absence is not possible. Running the command "/absence" will grant you 28 days of absence, which is the maximum. A different solution would be to transfer your island to another player and have them hold it for you until you return.
