[0.18.27] Biter spawn in unreachable position

Hi, I found 2 native placement bugs(ie how did they get there). Annotation 2020-05-27 183830.png shows how they somehow crossed the water. Annotation 2020-05-27 1838301.png shows that it wasn't just a graphical glitch.
Separately, Annotation 2020-05-27 18383011.png showing a native on a plateau with no entrance/exit.

I've got the save file so you can verify I haven't accidentally filled in some land somewhere that would make it possible. I have tried uploading it through here, but it returns Error
Error parsing server response. about 3/4s of the way. Let me know if there is another way to upload it. Everything is up to date on my end as of this posting.
Thanks

stuff

Wild speculation: Is it possible that Biters are now able to cross 1 tile wide water gaps, as mentioned in this FFF?

We probably won't, it is only a minor change and would have a non-zero performance impact (a rough test puts the worst case at about 5%), but then again it is a fun way to surprise those who thought the 1 tile of water would stop the biters attacking, and it kinda makes sense they can walk over it just as the player can. Well we will see if there are any issues with it in the modded cases before any further consideration.

Not sure if this is considered one tile? When I try crossing there I can't.

Not really a bug, and not really worth looking into
