Sabotage mission, different timer

[Hidronic]

 During the sabotage mission, Sometime there are different timer to each player. Today I can't take the screenshot but it really happen to me.

First case there are no timer for all the player when completely sabotage of reactor. We've try to find the hidden caches but suddenly mission failed without any timer.

Second, this is the most problem case. Only one or few player appear the timer, and when reach the time. Player who appear the timer will be failed after complete the screen. The other who not showing the timer or message is fine to complete the game. SO... I lost my reward after timer count zero... Nobody reach the exit zone...

 Second case sometime when reaching the timer count zero and showing the mission failed but remain the game. This case can get reward after finish the game.

Why this is happen?
