Creature found while exploring ?

[Meaowy]

My creature went exploring and apparently found a creature, but the creature it found won't show up anywhere in my collections. I checked if it was just an accessory, but it didn't show up there either. I have no idea what to do, where did the creature go ? Is it just a glitch or am I doing something wrong ? Please help

*for some reason I can't attach an image of the notification that showed up when my creature "found something"

Hey ! I found Crepuscule in the group of november of your creatures, is it this one you've found ?

[Meaowy]

Oh, yes it is ! Thank you so much ! ♥

I would have expected the creature to go into the same group as the creature who found it,
or just to the gallery and not in any of the groups

It should have be in the "no-group-creature" it's weird that it went in a group, but now you know where it is, which is the most important
