I lost the Pestilence Dog Tag I earned in a game due to a laggy server.

No more than 20 or 30 minutes ago, I played a game of conquest in Amiens. I am currently trying to obtain the the last four service assignment dog tags. In the middle of this game, I earned the Suffocating Pestilence dog tag, by "in a life, performing 10 kills with the Reaper affliction equipped." 

This is the last task in this service assignment that I had to do to complete it. I got it, I was very happy. Later towards the end of the match, the server got super laggy, however, I didn't get kicked out and everything seemed in order. When I went to check my progress in the service assignments page, I noticed that it did not track. I thought it was a random connection problem, so I tried restarting my PS5. In so doing, I gave up any chance I had at capturing the footage of my game, but I just didn't think about that at the time. 

I went to Battlefieldtracker.com to see details of the match, but it doesn't even show up, but it is the same server when I played the last game that does show up on battlefield tracker. 

My linked account is Jay_The_Dog. I beg of anyone that can help me to take a look at this. This is one of the hardest things to do in this game. Please, somebody help me.
