Aim9m and aim7m inconsistency

Is it just me or has the aim9m sidewinder and the aim7m sparrows just been really finicky lately, some examples are the aim9m going after a single flare pop (a aim9m would be tempted but would power through) and the aim7m just completely diverting from target even with a perfect radar lock

I accidentally typed aim9m

Right here, I meant to say aim9l
