To the person who was asking about metal not being there, if your on single player it takes awhile to respawn. If you look up on google "scorched earth reasorce spawn map" it will bring up a map and you click the reasorce your looking for, and it will show you the areas where they are. Also, random tip, if your on single player on xbox, if you quit ark while playing it, and then rejoin, it takes you back to your last save. My brother and i call it relogging. Reloging has saved me countless times. So this may or may not help your problem, if it does, good for you! If it doesnt, thats all i got, if it doesnt work, i have no idea.
