The sound effect that is heard when a consumable wears off is not happening at the correct time. The duration of consumables such as engine boost has changed to 15 seconds from 30 seconds, but the "engine boost wearing off" sound effect is heard 30 seconds after use, not 15 seconds. There is 75 seconds left on the engine boost cooldown timer when the sound effect is heard.
Reproduce this bug:
Use engine boost consumable.
Wait 15 seconds for consumable to wear off and listen for sound. It's not there.
Wait 30 seconds from use of consumable, until approximately 75 seconds remain on cooldown timer.
Listen for sound effect.
Hear it.
