Why is RInterp To breaking mouse rotation?

Hi, I’m new to UE4 and have run into a problem. I created a player-controlled pawn for a top-down shooter that rotates towards the mouse cursor, but it snaps instantly to the direction of the cursor. This wasn’t quite what I was going for as I wanted to control the speed in which the pawn turns. After some digging, I learned that the RInterp To node was needed to smooth out and control a pawns turn rate. Unfortunately, when I implemented this node, very strange behaviors started to occur. When the Interp value was set low, the pawn would only rotate a few degrees towards the cursor, stop, then start stuttering. When I set the Interp value to a high value, the pawn would snap to the direction of the cursor and again would stutter. I’ve yet to find a value that works in the slightest. Included is a screen shot of my blueprint to help figure out what I did wrong. I would be very grateful to anyone who can shed some light on my predicament. I’m currently using UE4 4.7.5.
