no mini-map & no map in menu

The Mini map should be available in campaign mode. I play mainly single player. i find it challenging and i normally play on the hardest level available. I have also had problems  with reloading, I use a mouse button as my alternate, but sometimes when i try to reload i have to use the R because the mouse4 doesn't work. Also when picking off guards at the hanger , there is a flamer that i shot in the head 7 - 8 times and he still doesn't go down. The others i hit once with the same sniper rifle in the head and they are down, even those with helmets on. The flamer i shot in the neck, bare skin. and head with no helmet still won't go down. I have all the BF games but this one has allot of bugs. I guess ill have to stay with games on steam. It gets very frustrating.
