0009644: Miners teleported from the bottom of the channel into a tree
On two separate occasions miners that were ordered to dig 5-tile deep channels teleported from the bottom of the resulting moat into a tree nearby. This happened twice in a row, with different channels (on different sides of the bridge) and two different trees.
1. Dig a channel about 5 z-tiles deep.
2. Miner that is digging it teleports from inescapable 5-tile deep moat he just dug into the branches of a tree, that is several x-tiles to the left, and is stuck there.
3. Dig another channel.
4. Another miner teleports to a different tree.
No tags attached.

They didn't teleport; they climbed. They most likely started climbing because they channeled out the floor they were standing on, and they ended up in a tree because you probably don't have any defined meeting areas (which they use as a "safe area" to path to while climbing).

So now whenever the dwarves lose their footing they quickly climb the nearest tree?

I do have a meeting area in my dining room.

I've got this one! It hit me right after I saved. So I reloaded several times with recording on, and I caught a movie of it. They're DFFD uploads 12328 and 12329. On z-16, notice the miner popping into existence just south of the westernmost microcline wall, where he's completely stuck.

Sadly, I can't replicate this bug reliably. It took me five or six tries of reloading that save to get the movie.

That's not teleportation, that's using the ramp he just dug next to the flooded ramp on z-level -17 that leads to z-level -16. And he's not stuck, he uses the diagonal-climbing-into-downstairs bug (0008383) to "escape" back into your fortress. As to why he does that... the only sane exit is blocked by another dwarf in a narrow hallway. This causes our hero to use jump/climb pathing to find *any* alternate route to avoid the inconvenience of sharing a tile.

0006586 covers dwarves climbing into trees for little apparent reason.
0009252 covers dwarves not climbing back out of trees for even less reason.
