Mooncalves missing?????

[Happi]

Hi, I seem to have lost all Mooncalves, they just no longer exist.
I had previously caught 2 and went back to get different colours and I have been to all the beast dens and not 1 in sight, they are just.....GONE.

Has anyone else had an issue similar to this or whoever took them, please put them back.

Thanks :)

I have that one time during my playthrough. Fix it by leaving a re-entering vivatorium.

Don't forget that they only come out at night.

If you found them during daytime, open the map and shift to night will save you a lot of time.
