Summary	0008667: Miners climb out of vertical chutes while digging, refuse to continue

Revision	2014-12-26 11:00 by lethosor
Description	I'm trying to dig a drop chute through ~ 130 Z levels using the regular technique (channel straight down) but it's proving to be difficult in these recent versions. First, if I just channel down then at some point the miner gets "bored" and climbs back out of the hole. This happens fairly quickly, like after only digging down 5 levels. Once he climbs, the bottom of the hole becomes off limits for future miners. In other words he can climb up but will never climb back down. To avoid this I tried sealing off the top of the hole with a door, to help him focus on his job. Eventually though I get an announcement "Urist cancels Dig Channel: Dangerous terrain" and he stops mining. What has occured is that he is now stuck 1 level above the bottom of the hole. Either he has grabbed onto the wall to avoid falling, or he climbed back up after falling. He then refuses to mine any more and needs to be extracted (I can do this by unsealing the hole -- he then climbs back out. The workaround for this, I suppose, is to dig some stairs adjacent to the chute.
