Well, thanks for the attention.

Yesterday the bug automatic solved it self with no workaround or reason after you answer here, but we knew that could happen again, so i chose to wait until it happens again.

Then, in 10:10pm (here in brasil, BRT) the booster has ended and we turn another booster active.
Since the activation, nothing happened until 8:10am (Again, BRT) when the bug started to happen again.

In 8:10pm was only for me and after 4 or 5 T-hunt only reciving 0 renown, the bug started to happen with my fiancee (Opsuh) too.


So explaning a litte more to solve some questions for you.
We play a T-Hunt in elimination mode, as usual. In dificult mode, not in realistic to be more faster and easyer. And after kill every bots, playing more than 1 minute by round/match, when we see the screen of get the renown, it just says 0 as in the screenshots.
We restarted the internet modem, pc and cleaned the temps files, and nothing solved it.

After we activated the booster, at 10:10pm of 29/12/2021, we goted like 15k of renown, and the bug started.
On the lobby or game menu, its normal, when we quit the match/round of t-hunt, my renown are normal, with nothing more and noting less. And its everytime like this.
We never received the renown of the T-hunt that showed "+0 renown".
It is not a visual bug, we just dont recive the renown.

I dont know if you can see our matches, or anything like this, but in the last 50 min ago the bug happened as every other time. If you can see, after 8pm (BRT) in 30/12/2021.

At this Christmas event, my fiancee and I are playing a lot of T-hunt with renown bosters.
And for both of us, at some point, the renown became 0 (zero) for each round.
We played 3 hours before sleep, and when we woke up, we played 15 minutes, and then this bug occurred

This happen, like, every day that we turn on the booster, when it gets closer to its ends time, this bug affects us on every 1-day booster, and didnt happened with 7-days booster as far as I remenber.
We do know that the bug will begin when the renown of the T-hunt is like, half of the amount that we were earning. Then the following round of t-hunt gives us 0 renown.
It happens at a time for me, and some t-hunts later for my fiancee.
We only tested on Ellimination T-hunt. And when begins to happen in t-hunt's coop mode, it happens on singleplayer too. (We didnt teste on t-hunt bomb mode or t-hunt hostage mode)
In online, quick match, the renowns are fine, with no problems.

There is some way to solve this bug, or is it a feature to people dont farm like that? And if its a resource of the game to prevent farm, there is a max cap of renown or what? (what makes it happens?)
Following annexed the screenshot of the bug, and the kills.
Booster is still on!

Sorry for the english, i'ma brazillian
