After playing Booga Booga for a few days I started to find some rare ores and was afraid to smelt them into bars until I came up with a strategy to keep ores safe while smelting.
Build a safe cage around yourself with desired walls (Best is ice or stone) and using many layers of walls is very helpful so players have a hard time mining through the walls.
After caging yourself in,place 2 huts facing each other leaving a crack for you to enter through.
One inside the 2 huts place 2 campfires (or 4 depending on the space) and place your ores to smelt.
Doing this people are not able to take your ores while smelting (they can easily do this with the camera and press F)
Using the 2 huts people wont be able to steal ores during smelting using the roofs.
Best for smelting Adurite,Steel Mix and Iron
