Before running the temporal sanctum, I organized my inventory a bit. I opened the map by right-clicking the dungeon key and then right-clicked the temporal sanctum waypoint.
Upon arrival, I noticed I received the first ‘5 minute’ AFK timer warning in the chat. I don’t know exactly when this got sent since I had my inventory open obscuring the chat, but I’m pretty sure it was there at the time I loaded in to the sanctum.
I proceeded to put my key in the door and entered the dungeon. I think it was pretty soon after I entered that I received the ‘4 minute’ AFK timer warning. Needless to say, I was a little worried, but continued onward (my key was already spent, so not much else to do).
Continuing through the dungeon, I made it through the first area and about halfway through the second area before the AFK timer did its 10 second countdown. I expected it to kick me, but instead, just nothing happened after the last ‘1 second’ warning.
Thankfully, nothing bad actually happened out of this bug, but for whatever reason the chat timer never got interrupted throughout combat and several zone transitions and it gave me a bit of a scare.
