Hello! It’s my first post there (and I signed in just to post it). While clearing the nest, a yellow item dropped, but it had a distinct gold loot beam over it. The stats are weak for the location (the Queen was 48 level - this thing is 15). What this visual effect can mean? There are the screenshots:
Welcome to the forum. 
Are you using any mods? Tools like Rainbow Filter?
No minimap marker, as special drops that pass your loot filter would create. Think this is just a visual bug based on where the item landed in terrain.
Doesn’t look like Rainbow Filter is in use, as there’s no changes to stat text or item names. And I don’t believe the mod changes loot beams in any case, as that would take more than the localization changes that Rainbow Filter involves.
No - I don’t using any mods.
Actually, I noticed: a “glowy” effects in my game (like, for example, from the tips of Bloodsworn scepters) are disappear much slower (may be over 10 seconds) - so could it be some visual “special effect” which appeared and got stuck? But even then - this thing lasted much longer: it disappeared only when I left the location (when I came back - to check - the effect was no more)
Hmmm ive never seen anything like that either. Did you recently change your graphics settings, or get a new monitor or graphics card?
No. Both graphics settings and monitor are old, and graphics card I changed in the February of the previous year.
are you using grimtex or reshade? dpyes?
alternatively mebe it’s just a simple file verification fix thing
No. The two Expansions aside, my game is as vanilla as they ever get.
And what’s you mean by the “file verification fix thing”?
it’s a thing you can do in steam to check all game files are present (and not corrupted i think?)
right click game in library, properties, installed files, verify
*galaxy should have a similar feature if you use GoG version, but i don’t remember where it’s located, probably similar steps
I checked it - all the files are OK
I’ve seen this too but only on the weapons of Bloodsworn cultists. The red glow lingers for about 10 seconds after the corpse vanished. Corpse persistence setting doesn’t matter, but the timer stops when you leave the Tomb of Korvaak, it resumes when you enter again. I reported it a while ago, but I guess such a minor thing that most people won’t even notice doesn’t have a very high priority when an expansion has to be shipped 
That golden glow around the ring though, never seen anything like it. Looks like the magic sparkle particles got flattened/widened somehow, maybe because the ring landed in a weird position on that egg cluster thing.
