Mods deleted

I think the only option is to contact Support. I'm sorry to say, I wouldn't be overly hopeful. The time that has lapsed probably doesn't help either.

I just came back to the game after 9 months off and found that ~1/3 of my best mods have disappeared. They were deleted from my characters and my load outs. Is this a thing that happened while I was gone? Can they be recovered?

You should go to EA Answers HQ and post your issue. I agree with the above, very hard to get a resolution for this one as they stated the bug was fixed but a fellow guildee got nothing sorted. I have to say its likely you will have to farm mods to fill the missing ones.
