It seems that with this code change, when you use a Tool which has a chance to break, such as the Noiseblaster, it removes/deducts the tool each use from the inventory 100%, every time, even if the tool didn't break (when the 'tool is broken' text happens at the top), which is not how it's supposed to work... Before, how it was, is that it would deduct the tool after use, and if it didn't break, would give it back to the player on Edgar's next turn, and if it did break, would not give it back - you could see this happening in the inventory between the turn of Edgar using a tool, and his next turn.
We are born, live, die and then do the same thing over again.
