So I have just been snubbed of enough Animus to progress in a dungeon for the second time in as many days.
The first one only lacked 1 little glowing ball but the second one was missing a whole mob to kill,
Do not remember the first dungeon but the second one is Dead Man’s Dredge.
I have walked through it 2 times from start to finish w/o finding my missing mob and I did the same in the one yesterday w/o any luck.
Am I alone in this? Am I missing something? What does it all mean?
didnt happen to me since s1. i think people just rush ahead too fast and dont pick up the orbs, which wont show at a certain point anymore.
But will the de-spawn? I walked those dungeons up and down looking for them and nothing.
it happened to me once that i rushed ahead too fast. For me it didnt despawn, but it was quite a search, especially since it was one of those rather large prison maps.
Dead Man’s Dredge is like a 2 minute clear to get to the door and I find it hard to accept that from never missing an animus ball to missing 4 balls in 2 days. But sure it can happen I suppose 
well i cant know for sure about your case, i can just tell about my experience ^^
I had this happen in S1, a number of times in fact. Was very annoying, I made a bug report or added to an already existing post in the bug forums. I haven’t run into the problem since S1 though. Not saying your problem isn’t legitimate, I just personally haven’t experienced it yet.
Best you can do is try to thoroughly search every nook and cranny in said dungeons, if you still can’t complete it, make a new bug report in the bug report forums. Be very specific, dungeon name, character class you’re on, etc. As dumb as it may sound Rogues had a problem using barrage on the boss of dungeons where if barrage killed the boss it would bug out and the dungeon would never complete. Was extremely annoying.
Either way good luck, if it is a bug hopefully it gets fixed soon.
Yeah. I will see these two incidents as a write off and if it happens again make a bug report, mostly coz I cannot remember it all now to that detail oO
It happened to me 3-4 times in eternal during season 2. Just 1 time during season 3. I think one of them was not animus, it was “slay all the enemies” phase 1 enemy missing and nowhere to be found.
My favorite task for sure, not at all annoying after you been killing all them red dots and one is missing. I am so sorry this happened to you.
oh now that this topic up, i do remember something from s2, where needed mobb spawned behind the fog wall.
but yea, didnt hear these things so far in s3.
yes i had also this season in 2 nm dungeons. no way to progress this bug unfortunately.
This problem occurs many times from ss1. I told in this webboard once but no one cared.
I had it happen the other day to my seasonal character - I walked back through the entire dungeon and I had not missed anything. I don’t recall which dungeon it was but it was one where there was a reward for a Barbarian character.
I thought that some (or all monsters) teleported to the character at some point when a dungeon is cleared out?
This is still happening now even with the new patch. Betrayer’s End , not enough animus … but no more enemies and no animus on the ground or in the minimap
You are not alone. I’ve encountered this bug more than a dozen times, including 4 times in the WT3 capstone dungeon. Every time, I re-walk the entire dungeon (often multiple times) to confirm I haven’t missed anything — there just is not enough available animus to complete the task.
I’ve been reporting it in the bugs forum since launch, but it’s still not fixed! 
I last encountered it 2 days ago.
An easy solution until they fix the bug is to just over-supply animus in the dungeon — extras wouldn’t hurt anything.
