NOTE: This is in the Orc Fortress fork of the Masterwork Mod.

They seem to be going into stealth mode spontaneously and not reemerging. As a result they move incredibly slowly, most only able to complete one or two tasks before needing to eat or drink. This doesn't go for all units, however: there's a legendary bone carver who is zipping around at half the speed of light. Can I please get some help, this was a really promising save! If it makes any difference, I was visited by a necromancer with some Drow zombies. Most of the Drow zombies were killed (I think) and the necromancer ran off. Problem is, the Drow were able to ambush individually, so are the orcs trying to hide from the zombies or something?
