Issues with Mouflon offspring

[Nathan Flaminio]

Four sets of offspring have disappeared, despawned, ceased to be, with no signs of death or wild ones running anywhere around the base. 

The original pen was an open-air, fenced-in pit. The new one has full walls and a ceiling, and is very well-lit. There are no gaps, no dead bodies or bones, no way for them to get out. 

The adults have not disappeared, only the babies. 

Anybody else having issues with this? Any mods that might be causing problems that anyone knows of?

Four sets have disappeared, as in the same has happened on four separate occasions? That would be fairly consistent.

The game doesn't track regular entities in logs, so it's difficult to say much of anything with certainty. If you want to verify that the sheep are actually despawned, you can try using the /entity find e[type=sheep-mouflon*] command to get the positions of all mouflon sheep within rendered chunks, which will also tell you if it finds any dead sheep. Optionally /entity find e[type=sheep-mouflon*,range=N], where N is the search radius in chunks, if you want to limit the seach to a shorter range. It will not be reliable if some time has already passed after the sheep have gone missing or if you have a lot of wild sheep around.

As far as I remember, even open-air pens need light to prevent despawning (especially if you're playing with a longer day cycle, since the despawn behavior is concerned with real time passage). But if the issue has occured in the new well-lit (should be light level 8+) pen as well, then I don't think I'm able to explain it as anything other than a potential bug without some additional information which can probably only be obtained through some proper debugging.

Having looked into it further, I've found that this is actually not the case. Animals should only despawn when underground or in other unlit, enclosed spaces, so they shouldn't despawn in an open-air pen.

I've done a bit of debugging, found a different issue, but failed to reproduce this problem. If it's not mod interference or some other bug, then I have no idea what could be causing this (may be worthwhile to know the exact mods you're using and your game version at that point, though I'm not sur there's a good way to test mod interference quickly enough).

Yes, four separate sets of offspring over the course of several in-game months. Every set so far. Only the young, though, none of the adults. 

There were lanterns around the open pen, no dark or dim areas. I'm not in the game now to check, but would estimate no lower than light level 12. The new pen is 7 x 7 x 4, with a lantern hanging from each interior outermost corner, plus windows and a glass ceiling. 

I tried flying around in Creative, but did not find any Mouflon in a pretty large diameter. I did find Valais in the area that were not previously there, and considered the possibility the Mouflons somehow morphed into Valais, but felt that was probably a stretch (though I have seen weirder things than that in games, lol). 

I'll try the commands the next time I'm in the game, thanks.

can we see a screenshot of your original animal pen? and make sure you check caves/pits nearby too, that's where all my escapees tend to congregate.

I blame the Chupacabra.

I don't have a screenshot. 

It was a very simple 7 x 7 x 4, rammed earth walls chiseled so there's no lip to get on with maple fence around the top. Low fertility soil for the floor. Flat ground, flat walls. Two large troughs on the southern wall. Lanterns on all four corners. None of the four adults despawned/got out/died.  

I have checked nearby caves, not in their entirety, but no bodies, no bones, no live ones in any that I have searched.

I more inclined to believe it was a Hodag, or possibly the Rhinelapus...

[Nathan Flaminio]

I used the /entity find e[type=sheep-mouflon*]

There are no lambs in the area.

I keep telling people Herobrine emigrated.    But no one believes me.

Update:

Was just in the pen to milk the ewes, and a lamb was directly under a lantern, but tooltip stated "deprived of light, might die soon" (or something very similar to that). 

Something is causing the lambs to react like it's dark even though it is not.

Was it a lamp on a fence? I think they do pass some light through, but maybe it got cut down to despawn level.

That sounds like a valuable clue for the Team: Issue Tracker
