Okay so for a temporary amount of time earlier today I managed to get on the eShop and input DLC codes for both Sonic Lost World and Batman Arkham Origins. However when I clicked the "download" option THAT'S when the error message decided to pop up, and of course the content didn't get placed in my download mangement. I manage to get back on the eShop again a few minutes later and thankfully found the recepits for the transactions and (after a minute or two of loading) the "my downloads" section showed that it did save the fact I have redeemed the codes and they are under my ownership. Now this is well and good, but when I clicked to redownload one of the items (the NiGHTS DLc for Sonic) it told me something like "item is already on the system, download again anyway?" and not sure what it meant I cancelled and exited the shop (and the shop's been down for good since then).
Now I did already have the Yoshi's Island DLC on my Wii U so that did show up in my system memory as "DLC" for Sonic Lost World, and just to be safe I decided to delete the content (the Yoshi DLC is free anyway), but since I can't access the shop again I don't know if I'll end up getting that message again (and the dowload mangement section still shows no activity of any items being downloaded to the system since the Christmas outage that's still ongoing as of typing this). So just wondering, was that "already on system" message concerning at all, even though the content itself did not get downloaded at all? (also worth noting the data section for Batman Arkham Origins is only showing my save data and the title update, no mention of DLC)
Thanks in advance, I just want to make sure I didn't mess something up by redeeming the codes and then getting an error only after selecting the "download" option during the code redemption.
