Somedays the Game feels different

Anyone play Halo Infinite one day and do fine, no issues, aiming feels alright, movement ok, then other days its like your settings just straight up changed, ive been noticing this more often where i just get on and i feel slower, my aim assist is worst, and nothing feels right, i know back when Ranked came out there was a bug that caused peoples custom settings to reset and caused alot of controversy and issues, wondering if this is a random bug that happens not just rank but other matches at random
