This one is weird. I got it too the other day, but I was modding so it was probably my fault (don’t know what causes the error).
This bug with the hearthlings idle and/or stuck in the ground is one of the first things devs will have to fix when they return from EVO 
The AI seems to be going crazy when there are too many hearthlings, and as they revamped the AI system for Alpha 11, it’s normal that there are some bugs…
I’m also getting this bug every time i start a new game, doesn’t matter how many hearthlings i have and in fact i usually have around 8 when this happens. it doesn’t matter if i avoid custom buildings or not. i’m not getting any sinking hearthlings though, it’s just a crazy surge of lua usage and my hearthlings will just not move, and eventually start to starve. also hitting F5 (or F3, I’ve tried both) to reset the pathfinding doesn’t seem to do anything.
So in the latest branch of the game, there will be usually 2 hearthlings who just freeze in the middle of my village and stay there till they starve to death. Often buried up to their heads
I got this message:

Game is stopping and starting constantly, I posted a thread about this before, but you guys updated in a new alpha and noted that these problems were squished.
Hope this helps,
Thanks
This is a reported bug. Are you playing Alpha 10.5? I’m pretty sure they fixed that in Alpha 11. (Though it is still unstable.)
Don’t know what caused this, or how to recreate it. I was placing chairs and tables, when a goblin and undead attacked me at the same time. I went into town defense mode, and two of the same engine errors popped up.
I discovered that also but unfortunately it only works for so long. My game is now completely unplayable because everyone is frozen. I noticed it only started happening when I paused my game so I could design a Town Hall. It started with one, then two until now all of my people are frozen. sigh I hope they fix this soon. I get so attached to each world then something always happens and I have to restart lol guess that’s what happens when you play an alpha game.
I think I had only 10 or so. Eventually on that save my lua was at 98%… well, 98% of the time and everyone was just standing on top of an unfinished house.
irony at it’s best:
two of my Hearthlings got stuck while eating in the dining hall (standard template)
I only noticed it when the first on died and checking the secon one I noticed he was in a sitting stance but not on the chair… instead he was sitting in the air right next to the chair…
since he had no food in his backpack I assume he got stuck after eating when he was about to leave the table
I already tried to free him by moving the chair but no luck… of course he is hungry now and about to die 
in my attempt to save my weaver Hearthling I reloaded the savegame and instantly got this error

and after reloading the Hearthling is stuck in the floor and only his head is above ground… so reloading made it even worse
I also noticed minor performance problems after I changed from alpha 10-5 to 11 resulting in short screen freezing and lag

5 minutes into a new game, just finished building the dining hall and after the first meal there poor Abi already got stuck after leaving her seat
this error just popped up when I tried to open the save menu… it’s a different one than yesterday

looks like the error is a result of a bad loop that re-iterates itself again and again as the error header seems to repeat itself adding one iteration each time
edit2:
heureka! after removing some chairs near Abi she finally got free and moved again… straight to the next chair to eat some food facepalm
but now my lvl3 carpenter got stuck while removing chairs… irony
but after all inventory was removed from the dining hall they all got free and moving again 
I moved a post to an existing topic: [Con] Alpha 10 - Males with outfits losing their heads! (all affected, mostly footmen)
just received my 17th Derpl… err… Hearthling and 22 days into the game without this kind of errors yet simply because I have not placed a single table nor chair nor bench to eat at
they have beds and all kind of workshops but so far none of them got stuck
compared to my previous world where I got stucked Hearthlings right from the start this seems to be at least one of the causes for these errors
Same bug, one worker went idle, even frozen in animation and starved to death. Second hearthling is doing it despite being put in a party and put into the dining hall.

I hereby can just re-confirm that Hearthlings can and will get stuck in chairs! [Dev 2513]
on my RAM stress test savegame I never placed any chairs and I went for 30 days and 27 Hearthlings without any single one of them ever getting stuck/frozen (and I stressed the game engine a lot )
but the second I placed some chairs they got stuck in them like flys in electric fly traps
either from leaving the chair after eating on it or just by walking by when another Hearthling placed a chair right on their foot getting them stuck in place
although undeploying the chairs freed the Derplings but meh… still no comfy eating for them
Every time i load new map i can play untill i save the map. After which i get this error which causes some of my hearthlings to stop doing anything. And i don’t mean they walk around doing nothing. They are literally statues frozen in place.

Reloading the save caused the hearthlings to appear above ground again, but here’s the full log (44.7 KB) and save anyways
This is weird. The log says that CPP AI is off, but the error occurs in code that is only executed when CPP AI is on. Any chance you changed the setting without closing stonehearth?
Yes, I turned off CPPAI without restarting the game
