I triggered both Demora and Dia earlier this evening and decided to try to fight them with experimental/underlevelled teams. I ended up running before finishing the fight - Demora was still there (and to my knowledge, Dia as well) and exited to swap teams.
When I returned to give them a thrashing, Demora had vanished! (so had Dia.) I've been wandering around for the past half hour or so, but they're still MIA.


Edit: This morning Demora's come back - i didn't get a 'your presence has been noticed etc' message. Haven't checked Dia yet

I think that *may* be an intended mechanic, where if you exit the lost grove, spawns 'disappear' for a certain amount of time.

However, I thought I saw someone say that it was bugged and that sometimes it takes longer for the spawns to reappear.

So, when you exited to swap teams, they despawned for a limited time, but didn't respawn until after you had given up.

Ah, thanks! I knew the ones in the upper grove usually took ~15 minutes to respawn after exiting and entering again, but I wasn't sure I was fast enough to beat the 15 minutes getting into the caverns lol.

You're welcome.

I just opened up the caves portion and stuck my nose in and noped back to the grove so I didn't know if it was different for them. I also don't tend to exit and then reenter the grove in a short amount of time. (if I do exit, it is usually for things like festivals where I am going to be days outside the grove, not minutes or hours)

When you force exit out of the Lost Grove, you will encounter a time penalty on your spawns. I can't recall exactly the mechanics of it, but it generally starts relatively short and then adds up. I think it can add up to hours of extra time before the spawns show back up if you forcibly exit the zone repeatedly.

It's basically just a disincentive from 'teleporting' out of the Lost Grove as you are meant to exit in the proper ways.

Ah, thanks! That makes sense. Guess that's what the portal thingy in the barracks is for. x)
