This Stone Beetle became unselectable and stuck inside it's burrow.

 

I believe I caused this by knocking the Stone Beetle down or interrupting it on it's burrow hit frame or something.

Just reproduced it, it is caused by casting Knock Down on a Stone Beetle during their Burrow animation, I hit the Stone Beetle as they were burrowing up from the ground (rather than down) and that caused their model to disappear and become untargetable.

I haven't been able to time it to the burrowing up but I can consistently reproduce it on the burrowing down animation. It doesn't work with "Searing Seal", I suspect, because as a trap it only triggers after the animation is finished and the beetle is considered "active" again.

Yep, same just happened to me although I think I was using the druid's hold animal spell (forget what it's called).

Just reproduced this too.  Cannot attack the beetle but it can attack my party, wiped.
