Need more mobs in sabotages

[Jep_fr]

I was doing a sabotage with a void fissure.

First, the reactant was rare because there is a few mobs. Then the objective changes. It's become an extermination. We kill all the mobs. And we don't get enough reactant to open the relic. So we left the mission without ending this. You should add mobs in sabotage or increase the drop rate of reactant.

I will not do sabotage anymore.

It... happens. That is why I tend to bring Nekros to Fissures, it certainly helps when there are only a limited number/few enemies spawning in the tileset.

They do seem to have less spawns than other mission types.
