Dont know what happened but after the patch on Friday i cant use kill streaks. The only one i can use is the radar and ONLY as soon as i get any time after it just doesnt work. first i though it was server so tried different ones and it still the same. even restarted my computer to see if there was something interfering and it's the same. this only horrible when i get like a maximum nanosuit or gun ship and i cant even use it. If it helps im on the pc version and im not using retriever module.
