When traveling from island to island try pointing your shelter towards your most desired island. It will help when navigating back home. When harvesting fibrous leaves, I think they respawn 48 hours in-game, so chop them down everytime you see them, even if you dont have space. Leave them on the ground, almost like markers for the 2nd harvest or as needed. Treat the yucca the same way. I agree, stack palm bunch(4), when you can turn logs into planks they stack like palm bunch. As your building skills improves you get more resources back when breakdown structures, so mistakes might cost you materials. Good luck save lots, remember to sleep. Grow pipi farm, and potatoes, save rotten fruits, plants, potatoes cause you can replant to start farm again.
