Has anyone had an issue with using a checkpoint and then being unable to trigger the encounter? We had originally played the opening of the encounter with the ads and triggered the elevators but had to leave. We tried several times to use the checkpoint to complete it today but found that there were no ads nor were we able to interact with the panel to trigger the elevators to complete the transversal. This is going to really suck if we have to keep starting from the very beginning every time.
