Issue
A player moves immediately, then visibly snaps to an earlier position.
Cause
The client prediction differs from server simulation, causing rollback and resimulation corrections.
Fix
Measure misprediction rather than hiding every correction. Remove client-only forces the server cannot reproduce, keep controller inputs deterministic, and verify network ownership assumptions. Smooth presentation carefully without allowing the visual character to drift far from authoritative state.
Verify
Test under simulated latency and packet loss while logging correction frequency and distance.
