Hmm, that's interesting. Could you find out more from your other LS members?
In our case it had no name, but was attacking people. In your case, it seems as though it was there, not attacking but completely invisible as well?
If it's true that it turns invisible, I wonder if it came back to the spawn point and was actually next to me while I was waiting for the ??? to reappear lol. Our RNG(s) didn't see the other one on widescan anymore either. Pop monsters must return to their spawn point before disappearing in my experience.
I guess I'll report these glitches on SE's comment thing, though I'm not sure if anything will happen as a result.
It really doesn't appear to me that this behavior is intentional.
