I can't edit beacons anymore, this blocks me from making it hide and appear when need. Already placed and configured ones still works, but i can't edit new ones. I'm making a adventure map, and that is essential to help the player traverse throughout the map and show new objectives.
Thank you for the report, we added a Trello card for this earlier today. https://trello.com/c/NLdq7Q1R/1190-particles-and-beacons-can-no-longer-be-customized
