Xbox 360 container detected

[Genkaaku]

I do not know what I did wrong. I've been modding like crazy giving away weapons to friends etc. Selling them in shop. Trying to make stuff bigger/smaller/and so forth. All has been fine until now.
I get this error saying in red: Xbox 360 container has been detected.

What does that mean? I tried to search for it in the search bar but not much help was there unless I wanted to go through like 10+ pages.
*Sorry I am lazy and do not want to go through that many pages*

Anyways I got past the problem by reconfiguring the memory stick and then reuploading my save etc.

What game are you talking about?

What game are you talking about?

I'm guessing "Dungeon Defenders" by the sound of it.

Oh sorry man! Failed to mention that.
Yes, definitely Dungeon Defenders. I haven't tried to mod anything else.
I still have no clue how in the hell I got that error. I was just curious as to what it meant and maybe I could figure out where I went wrong so I don't do it again.
Even though it wasn't that much of a hassle to re-configure my USB drive and then reinject the new saves. Haha! It just took longer than I had expected to mod.

I also happen to mod a lot! It's literally almost a full time job. Lol.
If you ever run across a lot of weapons made by Agro or Zeref somtime in the future......sorry!
