The new update is out now and the diggles actually dig so you may want to update the .xml for any custom diggles that you have. Its not hard to do, just add the following line to them: <dig mindistance="3" percent="5" ambushpercent="5" blockedpercent="100" minturns="3" maxTurns="6" /> Which is the default standard set of settings for digging diggles. (Although Some of types of diggles have higher "percent" and "ambushpercent" numbers; up to 40 {for Diggle Commandos})
