Sparkling loot/digging place, which cannot be interacted with

Hi all,

From time to time I come across places, which blink/spark as if there is loot there, but I cannot interact with those. Checked loot settings, enabled all- no luck.
Can it be those are “reserved” for later point in storyline or require specific class/spec to be looted? I’m lv25, Act2 on first character, if that is important.

Thanks in advance!

Could you share a screenshoot of said location or give a specific location.
Or you compare it here with hte worldmap andd if there is anything noted at the specific location (But beware of spoiler) :

Yes, I’ve noticed 2-3 places like this in Stauton Mine (or another mine) around Arkovian Foothills Rift - first zone in Act2 basically. I’ve encountered such before too, but these mines have more than 2-3 and got my attention.

Places don’t look like regular loot-places, which you need to hit. They are like buried and cannot be hit/interacted with. Just sparkling/blinking effect is seen every 2-3sec, when I look at the place

Another place - Four Hills, just next to the arena with the 29th lvl big guy
