Nothing should happen to them. You don't lose any items in your inventory and all the changes you've made to your world should remain the same. If you have built a structure far from your original insertion point, it can sometimes be hard to find again. If you know that a structure has disappeared you may be experiencing the Terrain Regen bug.
