I've been playing with the mod for a bit now and noticed that the workers don't drain their tools which led me to believe that this could be exploited. If it's not too much trouble can you put some tool drain in the workers and warriors? Also i play with alot of mods is it possible to add a config for different tools that mods add in such as tinkers construct tools?

Durability loss -- Negative. Trying to keep things simple. Constantly replacing your workers tools is -not- simple.

TC - tools - Negative -- cannot explicitly use items from other mods without adding a hard dependency (or doing retarded hack-arounds).

Thinking on it a bit further, it might be possible to allow use of other mods' tools through a config system (e.g. reference the tool-name in the config file to enable for that worker/npc type).

Still not too keen on durability loss though

would a config option work for durability loss - or no?

sure, except I would still have to code all the durability loss stuff
