I also noticed that the timer bar for the two robots (Arcane Watchman?) immediately after the Curator are incorrect. The timer bar counted down to 0 on our way to the Price, but in fact they hadn't respawned even after we killed the Prince and walked back.
They're right to an extent -- the arcane watchman pull *before* curator is a 45 minute respawn, those are tied to curator. The arcane watchman pull after curator is a 2 hour respawn along with all the library trash, and is tied to Shade of Aran. Both are named the exact same so there isn't a good way to figure out which is which.
Currently when the curator dies, the original arcane watchman timer is killed and they're set to a two hour respawn - but if you break for the night and come back the next day it doesn't know that the curator is dead and reverts to the 45min timers.
I'll look into having a way to remark a boss as killed for situations like that.
Looking at the minimap's zone text may help :)
