I cannot interact with the spirit, but there are about 8-ish ghosts about all with “problems” you have to discover. They all also seem to be connected somehow ( 2 are husband-wife, one is a trader, one was killed for a bad trade deal, etc.) and also seem connected to the area (some talk of Koa eyes another spider legs, which both Koas and spiders are present). Trying to figure out if it’s a test then the spirit is interactable. Some who have just walked up and completed the task may have walked in when someone else finished the test and the spirit was ready. Just a thought.
