Spire of the Watcher preactivation of nodes can bug the cicuit
When activating the nodes, you can "queue" up a node and activate the one before it to get both to be activated. If the queued node is the final one of the cicuit, it can bug out and not count as completing the circuit. In the instance of the linked picture, a reset of the encounter was required as progression was locked.
Just wanted to give a report of this, this is a rare occurance but does still happen.
