Sabre Spider bug in Mastodon Badlands

I'm experiencing a bug where the little Sabre spiders in this map are attacking me but I cant attack them back their health bars don't show up when hovering over them either but are able to dmg me. its not all the spiders just some of them are doing it while glitching around an what not. (Idk if this is where to post these types of issues so if wrong place sorry about that haha)

I've run into the same issue. A cursory glance at Reddit also indicates others have as well.

The spiders in question glitch around (like they do their walking animation and stutter forward an inch, then glitch back to their original spot, and do this over and over until they seemingly get "unstuck" and start following you again).

They can damage you, but mousing over them does not highlight them in red or bring up their names/healthbars, and player attacks (including AOEs) do not seem to damage them or apply ailments.

If you run away a sufficient distance, most of them stop following the player, but a few sometimes do. If you stand by a waypoint far enough away from their spawner, they will walk up to you and stand there, doing nothing. Interestingly, in this state, collision with the player model seems to be still active, except the player can also "glitch-walk" against them (meaning that if you walk directly into them, you will start to stutter over them, then glitch back to your original spot, similarly to how they were doing near their spawner).

Using a Portal or Waypoint to teleport back to town, then back to the Mastodon Badlands, does not reset the spiders or cause them to stop glitching. It did, however, cause the spiders that were standing near my character and doing nothing to despawn, though when I went back to the area with the spider spawner, the spiders were back there and continued the same behavior described above. However, this time, they followed me back to the Waypoint and continued attacking me right on top of it, instead of standing against my character and doing nothing as before.

Going back to town (the Ardura Caravan), using the Desert Map to travel to Keth, unlocking the Keth waypoint, and using it to return to Mastodon Badlands also did not reset the spiders (they continued the behavior described above).

It seems the only way to resolve the bug is to travel to a different region for long enough that the Mastodon Badlands map resets, and to hope that any spiders encountered in the new version of that map are not bugged in the same way.
