So I was trying to complete the clocktower earlier and when the ability to get out of overflow popped up, I took it and was sent to my server instance where there was only one other person. This was really cool as it allowed me to complete it without anyone blocking my view…
But I don’t think that’s what was intended…20+ people in the instance in overflow, no one on the server (Sorrow’s Furnace is my world).
My theory is that because the clocktower sends you back into an instance so quickly, everytime you do it resets the overflow timer so everyone remains in overflow even if the server has emptied out. But I don’t really know…I tried with two other characters and both remained in overflow until I got tired of it.
