Hey, first I want to say that I enjoy playing your mod It's great fun and adds so much more stuff to do that it's overhelming at times. I don't know anything about modding PZ, but when I noticed that survival axe cant be used by clicking on a tree, I went to check game files. And I found that: function ISChopTreeAction:isValid() return (self.tree ~= nil and self.tree:getObjectIndex() >= 0 and self.character:CanAttack() and self.character:getPrimaryHandItem() ~= nil and (self.character:getPrimaryHandItem():getType() == "Axe" or self.character:getPrimaryHandItem():getType() == "AxeStone")) end It's located in media/lua/client/TimedActions Don't know if it's any help, but I wanted to share.
