Forward extrapolation caused visible teleporting at every direction change (ghosts jumping ~1.3 tiles at intersections). Replace with lerp(prev, current, 0.5 + t/2) which starts the visual at the midpoint (max 0.5 tile / 12px lag) and smoothly reaches the destination. No jumps, no teleporting, minimal hitbox offset.
