Hello, I have create a 1.13 spigot server and had no problems. Until a player told me that there was an area that he could not break. I have removed all of my plugins relaunched the server and deleted all my server files except for the world I was using and It will still not let players break blocks in that specific area. When I tested the world on single player and on a vanilla 1.13 minecraft server, Everything worked fine. I am unsure if this is bug ---------- I have read and understood what was written here PPS: Bug reports which do not 1) contain a declaration of testing in Vanilla and without plugins, or 2) in the case of plugin API bugs, contain a minimal reproduction case (source + jar please) will be closed. Bug reports must contain step by step instructions to reproduce the bug from a clean server install with no assumptions or prior knowledge. Also make sure you include the full output of /version in your report. Please copy and paste this statement to the bottom of your report to indicate that you have read and understood it.
