My only complaint about it is there is like a 50/50 chance that it won't count as a nightwave challenge when you complete it with a friend.

Just like the first time they had this a while back, I completed with multiple friends, without touching the canisters and at the end only received one of the challenges as completed. What pisses me off the most about this is that last time it happened I reached out to support to see if they could correct the mistake because I completed it with my brother as soon as it came out and they let that thing sit for the entire week and then literally less than a minute (literally literally) I was able to complete it, extra hectic, extra annoying because I certainly didn't have the weapons to get this done or any ideal frames at the time. As soon as I complete it, support finally chimes in "oh hey cool we were going to look into this but it looks like you finished anyways, cool! thats that! later"...

I shouldn't have to complete the challenge multiple times for it to work and I just finished the 1hr kuva thing AGAIN with friends and only got credit for the one challenge AGAIN! I'm going crazy here. Kuva ain't my thing, 1-hr challenges are okay but not my thing... I'm not even going to contact support; I'll probably get the same outcome of them trying to outwait it.
