A catch-up frame or a hidden-tab step drains its events every EV_SLICE (15) ticks and each batch is stamped with that game time; the held backlog is emitted batched by the time it was drained at. The render engine then sees a late form fx as late and skips a change clip that would already have ended (a 转译基底·α no longer replays A_Die_C 16 s after its change).
