When harvesting, the system automatically moves your avatar to a specific spot. If the item is too near an edge, you will be thrown right off. Most recently I was thrown off a platform in Niiske Kook when scraping barnacles. Fortunately this place has a ladder, but in other locations, getting back to where you were involves a lot of annoying climbing and jumping. Please either change the movement rules or place items so that the system can't throw me off edges. Thanks!
