I have an idea for a modpack that adds maintenance requirements on machines for techmods such as EnderIO, IC2 etc. how hard is it to whip something up that will make machineshave some type of maintenance requirement on them like adding durability, randomly breaking, maintenance requirements for machines. lets say for example, enderio's SAG Mill will have a random chance at just breaking because the grinding gears broke. so you then have to use an item like a gear to get it working again by simply just right clicking on it. another example is to require machines to be oiled to keep it running every so often.
