This annoying sound of the system when character is not able to achieve the action cause of lack of stamina was applied.
Before that sound was used when square was unable to be terraformed.
Why You are applying such crappy sounds? Few months ago You applied some annoying horns for repetitive actions. You deleted it after 2 or one day.
Please cut off this "pubpub" stupido-annoying sound and pour some dishwashing liquid to the coffee of the guy who ordered to add those. maybe that will stop him from doing that again
.PS. I really like new environment sounds. Owls and grasshoppers are really damn good!
We are still lacking howls of wolves!!! Maybe even some legendary beasts like dragons or others which were described by the medieval guys as existing
... would be climatic.
