This problem has occurred on my server many times
I didn't find a way to solve it. I saw something about Astral Sorcery it in the logs file

[10:25:04] [Spigot Watchdog Thread/ERROR] [Minecraft]: net.minecraftforge.event.world.BlockEvent$BreakEvent.<init>(BlockEvent.java:133) [10:25:04] [Spigot Watchdog Thread/ERROR] [Minecraft]: hellfirepvp.astralsorcery.common.constellation.perk.tree.nodes.key.KeyChainMining.doMiningChain(KeyChainMining.java:129) [10:25:04] [Spigot Watchdog Thread/ERROR] [Minecraft]: hellfirepvp.astralsorcery.common.constellation.perk.tree.nodes.key.KeyChainMining.onBreak(KeyChainMining.java:97) [10:25:04] [Spigot Watchdog Thread/ERROR] [Minecraft]: net.minecraftforge.fml.common.eventhandler.ASMEventHandler_873_KeyChainMining_onBreak_BreakEvent.invoke(.dynamic)

Sponge/spigot are not supported.

However, I woould send this to the Essentuals plugin team to look at first, as they modify that trace later for that thread.
