Signal Jammers

[MagicMike51]

Finally could afford the MK2 Oppressor , flying around getting used to it i notice the the sight would turn red and beep . Investing i shot the "target" And game said i took out a Signal Jammer 1 out of 50. Continuing flying around i took out 3 more. I found a map of all the Jammer locations and went right down the list eliminating them. I took them out and when i reached the end of list at 50 the game said i only took out 44 - How is this possible ? I did the same thing with the playing cards and at the end the game said i was missing 2 . Just strange .....
