## Meaning

the replay was recorded with other simulation-affecting load options (the header's `sim`: the crowd backend, the navmesh's source, whether NPCs and vehicles are built in, the physics backend, whether behaviours ran)

## Fix

play it with the options it was recorded with (`--nav`, the crowd setting, an engine with the same features), or record again
