It may be a bug in this case, although it is easily avoidable if you know about it in advance. 

But in fairness to the OP, you really CANNOT know about it in advance. There is nothing in game that tells you about the exterminate timer, and someone getting lost looking for caches and thinking the objective is done and they have nothing to worry about, may get caught up by it easily. 

Look, the OP may be exaggerating when he says no enemies, but keep in mind that he completed the objective. While it doesn't always seem to work that way, from what I understand, the enemies are supposed to be more cowardly and spawn less frequently after you finish, since you broke their ranks. So if the OP was backtracking alot, there might not have been any enemies very near to him, even if they were on the map somewhere far away. I think this is the likely case here. 

He thought he was done, and was taking his time searching, something that he should be able to do. Yes, even in the event it was a bug there would be a way to prevent the timer if you know about it, but again, how could he have known about it in advance?

I am surprised at some of the people who seemed to suggest that he could have just kept killing, as if it was his fault? Yes, we all know how the timer works, but think of it from the perspective of an average player, who has nothing in game to tell him that. 

The game told him the objective was done and the enemies were dead, and the timer counting down that he hadn't killed anything was invisible. The Lotus tells him he can continue to search for caches if he's okay with the added risk, and encourages him to do so. He does so and he loses the whole mission. He's salty for good reason, and the whole exterminate timer is something that needs to be carefully looked at. 

He was doing exactly what the game was telling him he should do, and got penalized for it, and he had no idea that timer was even ticking down, that is completely unfair. 

And let's face it, can you imagine how salty you would be? Doing exactly what the game wants you to do, complete the main objective and then if you choose, finish the auxiliary objective as well. And then as you are searching around, you get told you have 60 seconds to make it to the ending, or you lose a lot of hard work, making your way through killing and carefully searching everywhere -- it's a big tileset. You panic. Adrenaline kicking in, trying to parkour as fast as you can to the exit... but alas, there is simply no way in hell that you can possibly make it, and you feel your stomach sink and a bitter taste in your mouth, as your adrenaline fades and you realize the game just screwed you out of all your time, because of a faulty timer mechanic that doesn't even tell you what's going on. 

This is actually one of the biggest problems with Warframe: Far too many things are not actually mentioned in game, and you have to go to wiki or ask on forums. That should never be the case for a game, that is just plain poor design. You should not need to "learn on your own" or "get told" as someone said above, the game itself should tell you. Simple as that. No ifs, ands or buts. Period. 

This is not the first time even where people reported that the timer suddenly appears on a mission when everything is finished and makes them fail.

I too remeber i have talked with a guy about the strangest bugs he has seen and he mentioned that he got the mission failure immient warning in a defense mission.
