Summary0008627: Animals which retract into body parts forget to come out
DescriptionI noticed this because I have a custom snail which is a grazer.

When scared by a threat, the snail would retract into its shell; but when the threat went away, the snail would sometimes fail to come out of the shell. The snail would then *starve to death*, because, since it's hiding in its shell and refuses to come out, it can't move.

I went into the arena and confirmed that this happens with vanilla bp retractors, though obviously they don't starve - they just get stuck in their shells indefinitely.
Steps To ReproduceTurn on morale in arena mode.
Spawn in an armadillo and a lion.
Take control of the lion and move repeatedly towards and away from the armadillo until the armadillo stops unrolling.

Really? In adventure mode, whenever I scare an armadillo or enchinda or something similar, they just spam 'rolls up' 'unrolls' at me.

The armadillo spammed 'rolls' 'unrolls' for a while, but eventually stopped unrolling. I took the lion to the opposite side of the map and jumped into magma, and the armadillo just stayed rolled up.

In dwarf mode the staying-rolled-up seemed to trigger a lot more easily, but I don't know if that's a result of dwarf mode, or a result of something about my modded-in domestic snail.

I tried that armadillo and a lion in arena in 40.21 but I can't get that armadillo scared enough to roll up. In fact, one or two armadillos (in succession) managed to kill my lion in all three tries.

How do make him scared enough? Are you using male lion and male armadillo or which combination? And "lethal" combat setting?

Maybe I am just not good enough at playing with lions.

Are you able to reproduce this in Adv. Mode? A save would be helpful.

The gender shouldn't matter.

I'm trying to do it in the arena, 40.19 version though.

Edit: Detros, did you forget to turn morale/fear on? I initially forgot to.

Tested with a human and I got the male armadillo to roll/unroll until he got stuck. Chased after the female one but she went into the fortress in the arena.

Took control of the male one (after moving the human a distance) and I was able to unroll normally.

Can't seem to get the female one stuck.

Pond turtle men (and women) don't seem to be affected, they also don't spam it like armadillos do.

Tried with echindas and while the male one stopped after a time, the female one kept going. However, I guess it got unstuck at one point since when I was moving around, I saw the male one roll up, but I didn't see the unroll message.

smijames: Thanks. that worked. Though I have to drop in some lava first to corner that armadillo so he stops running away.

Yes, once it seemed my male lion managed to stuck that male armadillo in rolled position. He was located on a ramp one level below me, if that is useful.

I have then found I (still being a lion) can talk ... which seemed more interesting thing to try then some un/rolling so there my testing of this bug ended :D .

I've got a save with a giant hedgehog *and* a giant echidna who are stuck rolled up in fortress mode. http://dffd.wimbli.com/file.php?id=10442 [^]

Still occurring in 42.04. Some additional observations from this save, in which the affected creatures are giant tortoises:

* I was able to build cage traps underneath the tortoises who weren't stuck too close to the edge. They immediately triggered the traps and I was able to train and pasture them. However, they're still immobile/stuck in their shells in their pasture.

* The trained female claimed a nest box, but wasn't able to move to it. I built one underneath her, deconstructed the one she claimed, and she lay eggs pretty much immediately. I've forbidden them. I'm preetty sure that she passed by a male tortoise at some point - the herd was wandering my property for a while - and am hoping that her immobility will count as incubation.

EDIT: The eggs did eventually hatch!

The save is at http://dffd.bay12games.com/file.php?id=11636 [^] . It was made before the nest box de/re-construction.

This issue still seems to be present in 47.05. I made a race of snail people and it's pretty much inevitable that one of them will eventually refuse to come out of their shells.

Here is the save of one of them being stuck: https://dffd.bay12games.com/file.php?id=15543 [^]
