I reset, but only in part due to the update.
The update was the push I needed.
My island had things about it I disliked that I could never change.
My airport was the gross yellow. My fruit was cherries which is the second worst.
Lots of rocks on the beach.
Shortest pier.
I've not reset up until now due to how much progress I had made.
I grew bored of how my island looked and thought about changing its layout.
But then I realised, that if I don't reset now before the update, I will never reset and have the dream island.
So I bit the bullet.
And im so glad I did as my new island is perfect.
Keeping your island if youre happy with it is logical.
But if you're not fully happy and want things only a reset can bring, then I think it makes the most sense to have reset before the update comes out.
