Did 11 tier delves yesterday and two times there were only 3 out of 4 gold piles with the nemesis mobs.
My friend and I checked the whole delve and they were nowhere to be found.
And a 3rd time it happened that we killed a group and the gold pile didn’t disappear and didn’t get the upgrade of the box.
I had the same with a Tier 8 Delve, couldn’t find the third group, even after backtracking the whole thing and double-checking everywhere, no sign of it.
Probably a bug (Like the one where Brann forgets what role he is and which curios to use at the start of a Delve), “Small indie developer” and all that…
I had this yesterday doing the Sidestreet Sluice on t8 bountiful. The last one just didn’t spawn. And I’ve also had an issue in the Underkeep where the mobs has spawned inside the wall, the main room in the middle and then down the stairs. Mob was there but couldn’t kill it.
It’s a bug if they dont spawn at all. The last gold pile just wasn’t anywhere to be seen.
Really the best way is to always submit a bug report when it happens, which delve, difficulty and approx where. Pretty sure they have set spawn points and just not triggering.
In one of the azh kahet delves , one of the gold piles was on a spike in the environment, which I couldn’t reach, so the mobs also wouldn’t spawn, a bit frustrating.
T11 Tak rethan abyss, one of the underpin’s brute charged into the coral and stucked upon evasion. I stuck in combat with it all the way till boss… Delves seem a bit buggy since reset.
