Somehow one of my players made it place mana spreaders, and it crashed with above log, when i enabled removing erroring tile entities in Forge that same log spammed the console and this is what the player saw. Once they broke the Rannuncarpus it was fine

edit: player said they had broken a mana spreader near it right before the server crashed, so i guess it decided a spreader was a valid thing to place down

same cause as #3215, fixed in next release
