- Remove the Simulate toolbar button (both Legacy + UMG widgets). Play / Pause / Restart / Stop now live exclusively on the Timeline panel, and the panel is visible by default (no more toggle button on the toolbar). Keeps a global Play button on the Legacy toolbar that opens the level outside the editor. - Move the grace-period / deferred-stop logic out of the TimelineSubsystem and into APS_Editor_PlayerController::RequestStopSimulation. This lets the timeline Stop button AND the UMG topbar simulate buttons share the same event sequence: OnEditorBeforeSimulateStop fires immediately (after RestoreBaseline), then a 500ms BT grace period, then StopSimulation fires OnEditorSimulateStop and cuts AI. New event OnEditorBeforeSimulateStop added to the editable interface with full timing docs. - Drop the early-return in TimelineSubsystem::Play when Tracks.Num()==0 — the timeline Play button is now the only way to start the sim, so it must drive StartSimulation unconditionally. - StartSimulation now force-calls SpawnDefaultController() on any pawn that enters sim without a Controller but has an AIControllerClass set, so AutoPossessAI=Disabled or race-lost possessions don't leave the BT unreachable. - Route the UMG topbar Play / Simulate buttons and the "simulate" command through RequestStopSimulation too, so every path emits the full event sequence consistently.
