Mass Effect 3 Multiplayer Bug List

Hello (sorry if it's the wrong section, i m new here).

something strange happened in one match in ME3 multi, i post it because i don't know if it is a glitch/bug, or a cheat from someone else, there's what happened:

i was in a gold match (with my palladin N7, i was using reegar carbine as shotgun and an M55 argus assaut rifle), the map was the one with an snow storm, but, few strange things:

-a lot of ennemies, even more than in platinium level, there where so much ennemies that most of the time i had to use my shield and melee instead of my weapons or powers because we where surrounded, it was like an black-friday rush when there's a special promo XD

-ennemies had the firepower of platinium level ennemies

-ennemies where very vulnerable, even more than in bronze mode, at a point that with only 3 shot from my argus level 1 i killed some phantom/ghost (i don't know how is it named in eng/us version of the game --> i m from france) and it was the same for everyone, so, the kill count and the score where very high for everyone in the match

-i had twice the ammount of spare ammunition i was supposed to have (so, instead of having like 160 spare for argus and 100 spare for reegar, i had something like more than 250 for each)

-there where all factions ennemies, exactly like in platinium mod

-in every whave there was an special objective (wich is strange, because, even in platinium, it's one objective for 3 standard waves)

-the ammount of EXP earned and credits erned was gigantic ( 350 000 credits, while golden is supposed to provide something like 80 000)



so, there's mi question: do you think it's a simple big, heavy glitch, or is it a cheat from someone else?

if it's a cheat ---> do i risk something? --> because i ve played in this match (i quit the saloon right after) --> does it account as accetary/complice/accomplice? 


i tried to take some screenshot of the results by pushing F12 and "impécran syst" but i don't know if it worked. (i don't know if origin provide screenshot option like steam does)
