Lets you configure corpse and carcass despawn times using worldconfig settings.

By default, reduces carcass (animal bones) despawn time from 336 hours (14 days) to 24 hours. Reduces machine (bell and locust) dead body despawn time from 24 hours to 3 hours (as these just drop their loot on the ground.) Increases drifter dead body despawn time from 3 hours to 24 hours. The time it takes for dead animals to rot into a carcass remains 96* hours (4 days) but can be configured.

*Chicks actually rot in 12 hours by default, unlike any other animal. They'll keep this value unless animalRotHours is defined.

You can customize the rot and despawn times by adding these worldconfig variables via the /worldconfigcreate command and reloading the world:

/worldconfigcreate int animalRotHours <value>
/worldconfigcreate int carcassDespawnHours <value>
/worldconfigcreate int drifterDespawnHours <value>
/worldconfigcreate int machineDespawnHours <value>

You can easily edit these variables once created by using the /worldconfig or /wc command and reloading. E.g.:

/wc animalRotHours <value>
