New updated not working

Error while compiling SkillTree: 'BaseDiggableEntity' does not contain a definition for 'SpawnLootListItem' and no accessible extension method 'SpawnLootListItem' accepting a first argument of type 'BaseDiggableEntity' could be found (are you missing a using directive or an assembly reference?) | Line: 18757, Pos: 44

Samesies.

Change 

var dItem = __instance.SpawnLootListItem(player) as DroppedItem;

to 

var dItem = __instance.SpawnItem(player) as DroppedItem;

And reload plugin

Solution above has fixed it.  Thank you.
