Vault Gnomes no longer laugh when starting a Vault battle

Platform: PC, Steam client
Game version: 4.3.0.07
Windows 7 (64-bit) SP 1

What happened?
Gnomes no longer laugh when starting battles in the Vault battle mode.
They used to laugh, so I assume that this is not an intended mechanic.

Video: (This video is of an older date, prior to 4.3 update.)

How to replicate this issue:

  • Play the Vault. (Gnomes should laugh, but they don’t. - checked in the 4.4.0.09 Update)

@Kafka
@Cyrup

Situation is still the same after the 4.4 Update - version 4.4.0.09.

Gnomes are no longer laughing at the start of a battle.
