Random Notorious Monster unclaiming

While working on Masamune Lv.85, I have been seeing issues w/ Cirein-croin randomly unclaim, however hate was not lost so this was not a "De-aggro". Noone was engaged with any other monster at the time either. Second time around it lost claim again not long after Provoking it during pull to camp.

Last night the same issue occured at Itzpapalotl, we spawned it, a little ways down the road going to camp, it lost claim, but no hate reset.

Please look into this as soon as possible, would rather not lose an NM to some random group over this without even being able to engage in battle.

Some things to clarify, just in case it is in fact "behaving as intended", as SE frequently replies:

did you do any damage to initially seat hate on it? In particular, any action that isn't just a quick volatile hate spike that fades quickly...rather something that has slower decay.

Are you absolutley sure it didn't do something to cause hate loss--something like Mayhem Lantern or Deathgnash are two examples that can cause instant loss of hate.

In other words...did you just pop and run, or did someone play with it for a few seconds and then run. If the latter, did it have enough time to fire off a move and you just didn't see it in chat?

Didn't do any form of damage to it upon spawning, did not engage and disengage, did not recieve any damage during the pull, and did not deaggro it.

It simply just went unclaimed while I was bringing it to our camp.

Not sure what the cause of this is, but it has happened alot.

then you didn't technically claim it. You aggroed it---two different things.

Actually, I think popping monsters give the same hate as initial claim. This is just a case of deagro though. If the monster can't act on you for some period of time (maybe something like 30 seconds) and you're something like 20'+ from him, then you are removed from (at least) the top of the hate list. If there is no one else on the hate list, the hate less resets and the monster turns white.

Itzpapalotl always casts Firaga IV shortly after spawn, as it is his only spell. This gives people time to get away and puts him far behind them, which is a recipe for deagro. You deagroed it.

If you run it through the water and get a little too far ahead of it, there's a chance it will deaggro.

Greetings Raka!

We can see why you would be reporting your concern as a bug but as others have previously said, it can happen depending on the situation. There are several reasons why the NM would have gone unclaimed and some of the players here listed a few. If there's any other kind of problem or concern, please don't hesitate to post. Thank you!
