Would you be willing to share your save with me ?

If so, please zip your saves folder and upload it somewhere like dropbox, googledrive or OneDrive and PM me the link.

I'm confused on how too do this

You can find instructions here: General Information About The Bug Reports Forum | EA Forums - 4965007 

do you need all my saves or the one that has issues?

Just the one that has the issue.

sent! (i think)

Thanks. I'll check it out as soon as I find some time :D
