Thanks for the laugh
Ani,
Ps: we've seen this behavior for long (Iwould not call it "bug",maybe optimization with unintended visible side-effects feature)... apparently, it seems that the AI server is responsible for this behavior. afaibt the spot you found is a "herd spawn spot" (other packs spawn more or less separately). From there, each one follows a given path. I was told, a while ago, that the server may "sleep" entities or maybe it's a rare bug that's triggered rarely. (The former makes a lot of sense, if you can stop animating entities to save power and resources... it's a bit tricky) if /when after some time, no "player" has been in the region....

Personally, I've seen this a few times (even, for example, in PR gates with yelks),
Of course, a dev chat could explain things better or correct this urban legend if needed
