Hey guys, I have a little bug on my server since few weeks, and im unsure how to fix it or what is causing it. About the bug, not every player has this bug, just 2 of 3 players are complaining. If a player want to place a block, its turning into a random block, lets say i want to place a crafting table, sometimes the placed block turns into sand or log. If i craft something, Items/blocks are moving randomly in the inventory or just disappearing from the inventory, a relog fixes this, after a relog the inventory is back to normal, but its annoying to relog every 5 minutes. I tried different Spigot and Bukkit builds. I deleted all player.dat files to make sure its not a corrupted player file. All my plugins are up-to-date. Any ideas how to solve this bug/problem?
