Character wont hold his orientation

Hey guys/girls.

Working on a duel stick top down shooter-ish game. Basic basic thing at the moment but…

my right thumb-stick on game-pad is used to control my actor rotation. which works perfectly until i release it. then he snaps back to the direction he was facing when he spawned in. i have limited skill or knowledge and am stumped at how to make this not happen.

Please help if you know how,
Thankyou
( oh here is my blueprint, its super duper simple but working. )
