No crash sound or custom engine sounds

Recently I launched Beamng and noticed that all of my vehicles with custom engine sounds made no sounds at all. Also whenever I crash there's no sound whatsoever. I tried clearing cache and nothing seems to work. The game also deleted about 100 of my mods for no reason when I launched it and I can't get anything to work.

 

try a vanilla vehicle to see if the sound work. nothing custom just a normal vehicle.

also if most of your mod got deleted, then its normal that all your custom config are not working properly.

 

Even when I delete the mods that I know have custom sounds and redownload them it still doesn't work.

 

Do the vanilla sounds work? If they do work, it is the mods fault (probably broken).
