I had something like this happen while fighting a blob of a boss angel. Not exactly sure what happened, but I somehow dodged right through the slade wall and outside.

I was doing a dodge and then suddenly found myself on the exterior of the tower.

I'm verifying that this is still present in 40.13. Just had 2 incidents of dwarves phasing through walls while sparring.

Can confirm this is still in 40.15. Had a barracks where the wall was shared with a volcano. Suddenly lost two soldiers and simultaneously discovered adamantine. Checking the sparring logs, one charged, they collided, then tangled together and tumbled forward, through a wall and into the lava. I wouldn't even call it a bug if they had broken that wall tile in the process.

DF 0.40.23 I had a Giant Weasel fighting a Forgotten Beast suddenly appear on the wrong side of a wall.

I'm not sure a save file will help. I have one from after it happened, and one from before the battle started.

[EDIT] As you can see the last thing to happen was the Giant Weasel being knocked backwards.

This is still present in 40.24. Had some soldiers sparring near the inner side of my 3-tile thick hollow fortress wall and some of them kept charging/dodging into the hollow part of the wall, and I had to dismantle the walls to get them out.

Edit: Might be a coincidence, but this seems to happen more frequently once the soldiers reach higher proficiency in their combat skills as they had never charged/dodged through the walls in the early months of their training. Also, the ones who warped through the walls had higher dodger/fighter skills.

Qrox: That's caused by them not sparring in the early months because IIRC they need to gain like 5 levels first before they start sparring at all. Or/also, with low level of dodge skill dwarf has low chance to successfully dodge, to wherever it is. With higher one he will more often dodge to nearby tiles, not checking if they are otherwise deemed unpassable.

Here is a save in which dodging/charging through walls is happening in version 0.42.05

I also experienced this in 40.24. It probably happens quite often I just don't notice it until a seige is going on or a hill titan is attacking. I didn't check the sparring log to see what caused them to teleport to the other side though. I thought it might have been related to the fortifications I put on the 3rd floor of my tower however I have floor grates in between the sparring dwarves and the 3rd floor. Also I don't think dwarves normally dodge up stairs.

Following link to DFFD contains a save that this is consistently occurring in, description below. DF 43.03

http://dffd.bay12games.com/file.php?id=12266 [^]

Dwarves training in Training Room on Z-158 will often suddenly pop out of the room and fall down to Z-151. Since this is a large fall they usually die instantly or shortly after the fall depending on the injuries. The bug seems to happen fairly consistently with this save. Last time I loaded this particular save the bug occurs after a few seconds.

Confirmed in DF 44.03. Militia commander and sparring partner were sparring. Commander's sparring partner charged, and both combatants tumbled through a single tile of constructed stone wall, no fortifications, and fell 30 or so z levels onto solid ice. Of course, they died on impact.

Confirmed in 44.09: forgotten beast was fighting a large amount of cave critters near 1-wide wall and eventually ended up inside an airtight sealed area.

Confirm for 44.10 also. Discovered magma sea after two sparring dwarves knocked each other through the wall of a volcano I built my barracks up against. Designating training areas leaving 2-3 squares to walls seems to prevent this issue.

Confirmed for 44.12. Kept getting heavy injuries, because dwarves were sparring in sealed 5th floor of a tower above ground. Relocating the barracks solved this.

44.12

Dodging and Charging can go through solid walls, only tested on 1 tile thick.

Enclosed with 6 floors above and 12 below.

Dwarf charging another when sparring.
Dwarf dodging.

Fortifications also can be dodged through.

@obliza:

This report is for charge attacks. If you have a save demonstrating a dwarf dodging through a wall you should log a separate issue and upload the save. When I tested sparring dwarves in v0.43.05 they did not dodge through walls:

I can confirm this also happened to me consistently. I created an above ground room with marble walls, all sparring was done in said room. about 30-40 dwarves sparring, every few minutes I would find one pushed through the wall and locked outside. I eventually resolved this by creating a 2 tile thick wall.

I've found the problem with the charge/tumbles, and it could indeed more rarely lead to teleportation over much larger distances. Fixed for 47.04.
