HELP ME PLEASE

my friend told me he had a way to get a bunch of XP fast, so i thought he just found a way to do missions faster or something like that but he told me to just load in a game with him, i thought we were just going to find a new way to do the missions really fast but he did some kind of glitch, it boosted me from level 49 to level 85 in just one mission, i thought he was just going to do the mission in a new way like just repeating extermination missions over and over, which was just another method of grinding in my book. I wanted to get this high level fair, not like this. What do i do someone help PLEASE

also im probably gonna get banned from this

😭

Edit: i forgot to say that i made a request to arrowhead so i hope they are able to fix it from that

Edit 2: I also forgot to mention that i got a bunch of warbonds from it too so i think that it just gave me the mission reward over and over again
