Fix non spawning NPCs and game crashes caused by vehicle seats
Re-enable mouse acceleration.
In the SPV3 Loader (launcher), go to Settings, then Advanced (bottom-right), and tick the box labelled "mouse accel".
It is unknown why the EXE patch to disable the game's mouse acceleration also affects unrelated script events and object velocities. This leads to some dropships flying in with no troops and the game may crash if you look around in a vehicle seat. By "vehicle seat", we mean any mission in which you start a pelican or when you manually enter a vehicle seat/turret.
