0000140: Miner cancels mine, and the designation.
When one of my peasants got stuck in a hole I did not rescue him but his mining labor was still on, when I told my other miners to dig out a new spot a job got assigned to the stuck peasant. He decided he can’t get to it so he quit the job and the designation got canceled.
Isolate a miner and try to mine some place he can’t get to.
If no miners can get to a designation than this glitch does not happen.

I think It has to do with all the pathfinding bugs.

I had a very similar problem come up, I should test a bit more but I think I might have a clue what is going on with this one...

Like you, my miner was trapped, I was trying to force him to dig a causality pit straight down with ramps. At some point he became thirsty and things suddenly stopped.

Repeatedly the trapped miner would start the dig action, I could see the tile blinking yellow, he would then interrupt himself with a drink task, when he realized he could not path to the drink, he would then stop and cancel the dig task removing the dig marker.

Thirsty dwarves should not be canceling dig tasks!

To completely isolate this, I removed the mining labor from all dwarves except the trapped dwarf and repeated the attempt to get him to dig himself out several times. He still failed to dig, too thirsty.

This doesn't reproduce now, so I'm assuming it was fixed in the intervening years. If somebody has a save just before a designation gets screwed up, I could use it.
