lith m4 relic too fast for reactant?

[ostemand]

i was doing a m4 relic with my friend, and he played banshee prime and i played trinity, so i gave him a lot of mana and he just killed everyone in the game almost instantly, and we went over the waves pretty quickly. I thought why we didn't get so many reactants, and at wave 4 we had only gotten about 4 reactants. So we thought that we would for sure get all 10 reactants because, how else could we open the relic? but we never got 10 reactants?? this must be a bug. We ended up having 6/10 reactants, and didn't open the relic? My theory is we did it too fast, and your game didn't expect the waves to be done so quick, so it didn't drop so many reactants for us??

I noticed in solo Lith Relic Void Fissure survival missions that it gets harder to collect 10 void reactants in the 5 minutes period after wave 2. After getting frustrated with not collecting enough relics to open in the 5 minutes period a few times I observed that void fissures only appear in certain locations and started hanging around near them. I also had to refrain from killing enemies before they have a chance to become corrupted. After doing these two things I have not had a problem collecting 10 void reactants in time. Good luck!
