So correct me if I'm wrong, but I believe the bosses take two hours to respawn while the chests take one. I usually run the zone by doing a sweep from one end to the other every hour or so, collecting the chests, and then the next time hitting the chests and the bosses. I've noticed though that sometimes I'll have one spawn that will take a much longer time to appear or won't appear at all until the next cycle. For instance, I did a sweep of the bosses once and Patheros wasn't there, but when I did the sweep for chests an hour later he was, despite my having defeated him at the same time as the other two bosses. And just now, the chest by Amelia didn't respawn, and it's been roughly half an hour since it should have.

This is, of course, ignoring the one chest that respawns at six hours.

And I think part of it, at least with the chests, might be that it seems to take a few extra minutes for the chest to respawn if it's an ancient chest? I've noticed the one by Morgana tends to take a bit longer sometimes, and when it does it normally is an ancient chest.

If they are respawning, there shouldn't be an issue code wise.

However, all spawns do have a variance. The longer the respawn, the bigger the variance. Is it possible that what's just going on?

It's entirely possible that's what's going on. It just isn't something that's ever been as noticeable in previous fests, at least for me personally, so it's seemed strange how long things were taking sometimes. Like it taking three hours instead of two for Pantheros to respawn, to me, seemed like it would be a bug since it's never happened before. ^^

And sorry for the ping! Habit.
