I encountered this about 10 minutes in (after SECOND round) I never started the third round until after the "inactivity" and I ended up taking the screenshot of the timer 5 minutes late due to me setting up this thread in the middle of the game being paused while I'm writing this.
I Don't know what might cause this, but I was using Grendel's 3 most of the time and honestly it could just be a droptable error in-game?
I will be rerunning this later to see if it happens again/continuing until rotation reset and reply or edit if it does.
I apologize for not really knowing what might cause this other than giving my speculation, it was an alarming occurrence considering I was not inactive until I paused the game to write this post And I'm pretty sure if you're inactive you don't get any reward for that round, but it gave me "round 3 reward" after round 2
EDIT: It happened again and gave me "Round 5 Reward" for Round 3 and said I was inactive for round 4 and just started round 4
