A bug report, for a bug...

What did you do?
- N-nothing!...well, we did pollute the planet...

What happened?
- A biter came to attack as per usual, but it stopped halfway it's attack to get stuck in trees.
- We let the biter be when we played, after 1,5 hour later it was still there, we named him Terry the tree hugger.
- I discovered this while playing multiplayer with friends. I decided to save for a possible bug report when I found it.
- I have no idea how long the biter has been there when I discovered it, it could have been there for hours or just a minute.
- It's been stuck there at least 1,5 hours, 2 save files are included at the bottom of this post, [ADVENTURELAND] 9 hours and [ADVENTURELAND_02] 11,5 hours into the game.


What did you expect to happen instead? It might be obvious to you, but do it anyway!
- Read in Friday-facts that biters got new path-finding behavior a while back where they will destroy trees and other things in their way if their path to their target is blocked.
- I experimented with the save(in download link), approaching the biter seems to trigger it to attack you, resuming it's normal behavior, also destroying trees in it's path.

Write down the steps to reproduce the bug if you know them.
- I do not know.
- Maybe using the same map string and putting the map under similar conditions could reproduce it, but then again this is at least 9 hours into the game.

Does it happen always, once, or sometimes?
- This happened once

If you need more info just say the word!

Something similar happened to me in a single player game. 0.15.6 at the time, but it was in the middle of nowhere, just flat land with some coal patches. A single biter had split off from an attack group and was just wandering aimlessly. I figured it was just due to railworld settings which prevent biters from colonizing/migrating, causing this one to get stuck somehow. I don't have a save however, didn't figure it was worth a bug report when the fix involved a U-238 round to the face.

Guy got stuck in dense forest. And it actually looks like I already fixed it (in 0.15.11) when working on another bug – the biter should now give up after a while.

So, I guess it's fixed.

Hi, I have a similar problem in the latest version (15.23), where a biter stuck in a forest moves in an endless loop for 1+ hours. This persists after reloading the game. Save, and log are attached. I'll attach a quick video in a minute or two.

Here's a video, including some F4 options.

Was fixed a few versions ago (just checked), appears that it might be 15.27 that fixed it, but there doesn't appear to be anything in that or 15.26 or 15.28.
