@EA_AticI have found a fix for this for my account!
PSA: It is a timed fix while this mode is out, so try to get in a match of Community Spotlight - Gunfight Royale before it is removed (I think Friday 1.27). It works easiest to get in a match on Gunfight Royale on a 2042 map and pick Sundance, otherwise you will have to get lucky on gadget rotation. (if it doesnt work on a 2042 map to get both grenades back, you'll probably have to get a BF3/BFBC2/1942 map and get lucky with gadget rotation to get the grenade belt with both scatter and AT grenades)
Since some of the earlier reports seemed to have indicate it was due to joining a weird portal game mode, the fix I found was from the same way.
I joined a lobby of Community Spotlight - Gunfight Royale (Super fun mode btw, awesome MANCOUR and DIRTEEBREAKS). Once I played my 3rd match (it was Arica Harbor, I picked engineer) one of the random loadouts gave me the Sundance grenade belt, but I had both the scatter and AT grenade (which I haven't had in over a year). I noticed it, and made sure to throw one in the air. Since there are no vehicles in the mode, it just flew up and hit the ground. I played out the match and won, and then left and joined a Exodus Conquest match with Sundance and sure enough, the grenade belt was fixed with both scatters and AT grenades.
