Whenever me or one of my friends joins my server, it crashes. We're all in the same location. I tried deleting our playerdata and that let us join the server, but when i teleported back to where we previously were the server crashed again. Can anyone please tell me why my server keeps crashing and how to fix it? Crash Report is below. Edit: I solved the problem, it was being caused by the new frost walking enchantment. I deleted the frosted water blocks under the player with the enchantment and the server stopped crashing.
