Quick answer: Unreal Anim Blueprint logging 'tick record mismatch' warning after state machine edits? Per-state tick records cache the state ordering - recompile to clear.
Reordered states in an Anim BP state machine. Runtime warnings: tick record state mismatch. Animation plays the wrong clips.
Recompile the Anim BP
Compile button (F7). Tick records regenerate from the current state list.
Or restart PIE
PIE caches tick records at startup. Restart picks up the new ordering.
Avoid reordering hot states
If a state is referenced by many transitions, reordering invalidates dependent transitions. Add new states; don't reorder old ones.
“Anim BP state machines are compiled. Edits between compiles can desync runtime state.”
After any state machine edit, compile before testing. Habit prevents the bug class.
