@ktkasumu There is a bug that was fixed for PC https://answers.ea.com/t5/Bug-Reports/FIXED-Save-Error-510-5bd7fa0b-6bbefeld/m-p/8427108#M109580 that we have not recieved on console. We should get this fix the next patch we receive for console, but it can be a ways off, as you know.
You can make a new bug report on the bug forums to report this 510 save error for console if you wish, but the fix was already pushed out for PC and the bug team should be aware of it already. Whether or not you create a new report is up to you.
I have received this error code on a few occasions, and I try to save a new save or save over an existing save until it saves properly. I know it's not a solution but my game does eventually save when I get this error if I keep at it.
