I tell a lot of people about my experience with this, but it may well not be your problem....
One time, I was looking at my Tangle Honey Largos playing with a Sol Mate (Slime Toy), and three of them pushed the Sol Mate further into the corner, where the fourth Largo was, and suddenly the fourth one disappeared, because it had been pushed inside something solid. Slime Toys may be a problem. I don't know if they fixed that one. It's also possible that other things can push Slimes into that corner, such as food, Plorts, or even other Slimes, though I haven't witnessed it.
Either way, having just 3 Largos in a Corral is usually safe, and 4 will last a while. 5 usually results in a disappearance every few days. I've never dared to go above that. I will note that I've never had that problem with Fire Slimes nor Puddle Slimes, so it may either specifically be with Largos, require more of the smaller Slimes, or not be part of those two's behavior.
