Hi there
@Trollsamaa, welcome to the forums.
Backup copies
Yes, there is a way to backup player and character information on the Xbox 360 (you can’t on Xbox One, but can on Xbox 360). I used to create copies onto an external USB drive all the time as a way to keep my files safe if the game had a blip and corrupted my save data. See these articles for more info (if your drive can handle it, I’d recommend making a copy of all the content):
Endless Musket Pouch (and other items the wiki may reference)
One thing to be aware of as your son browses the wiki... the Xbox 360 version of the game includes content up until the equivalent of PC’s version 1.2.4. Meaning that the 360 does not have the Endless Musket Pouch that your son is hoping to craft. There are going to be things on the wiki that the PC version only has, and that other platforms (like current-gen console and mobile) have. The Xbox 360 and PS3 are considered “old-gen consoles” and are no longer receiving game updates, while PC, “current-gen”, and mobile are still receiving updates.
So on the wiki, make sure that the item he’s looking at is included in the 360 version. He may be seeing items that will never be present in his game. One way that can help in determining this is when you’re looking at the wiki page, scroll all the way down to the bottom and look at the History. If the item was introduced in PC’s version 1.2.4 or before, the item should be on the 360 version. If the History says introduced in PC’s 1.3 or beyond, it’s not on the 360. The wiki is community edited, so while it does a really good job of being up to date, it can have mistakes.
View attachment 281803Here’s the History of the Endless Musket Pouch. Note that it was introduced in PC 1.3 (and therefore not on 360). The “console” notes here specifically refer to it being on Xbox One and PS4 only (not Xbox 360 or PS3).
Sorry to side-track so much to explaining the versions, but it may be that whatever version you guys were on before doing this recent update was actually the most up to date version. Terraria on the Xbox 360 was last updated in 2016 to the equivalent of 1.2.4 (however, it shows in game as update 1.09 since console versions are numbered different than PC).
Xbox Live?
Is it possible to try signing in to Xbox Live? Since the 360 wasn’t hooked up to the internet, I’m assuming Xbox Live wasn’t used, but since a previous member’s issue was solved by logging in, it was just a thought.
