Too many bugs in Deimos bounties

[WIkter03 1]

After update for about 2-3 patch the bounties start to get bugs more and worst than when they're release. 
-You might alway found Grineer's score increase multiply with out any kill infested or you use DPS frame killed all infested before them.

-The deffend area with out any hostile spawn in the area for trigger bounty for start the mission.

-Failed the deffend area mission by unseen hostile and deffend percent decrease multiply while you make sure there's no enemies nearby the deffend area. (This problem still found in other bounties too)

-Enemies spawn less or none in the mission that require to kill an enemies.
