It happened to me with my map too, i switched over too quickly to the map and lo and behold I ate my map and all the progress the map has on it. Meaning I was in the middle of the ocean with my propeller thing and no idea which way to fly towards land. So I just died at sea and had to almost start over on the closest island to where I had died. Ended up having to make a paper press, a smelter , and a tanning rack to make the map, then a raft and find my home location. What a pain it was. Just because I ate the map. There should be either a way to get the map back, make it indestructible or a way to copy all the areas you traveled already to a new map that you make. It's stupid to have to rediscover areas you already did. Would also be cool to have items that can be bound to you.
