'Error in a packet listener (send)'

[OpenSourceSlime]

Information

• Server Version: Purpur version git-Purpur-1385 (MC: 1.17.1)

• OldCombatMechanics version: 1.10.0, dev # 58

• Server Log File: Trust me. You do not want this, it's way too big because of the errors OCM rapidly sends. This is the best i can give: https://paste.sparked.host/irolopezug.properties

• OldCombatMechanics config file: https://paste.sparked.host/zojijukuru.yaml

Problem Description

It will throw out this error rapidly when a player is online and enters a world where OCM is enabled.

### To Reproduce Steps to reproduce the behavior: 1. Configure OCM for your worlds. 2. Go into a world you specified to OCM you want to use whatever 1.8 PvP mechanics you wanted. 3. See the beautiful errors, clogging up your log files and making them in a day 106 MB big. ### Expected Behaviour Well, of course i don't want these errors. Soon my used disk space will go from 12 GBs to 50 GBs because of the logs! ### Actual Behaviour

https://paste.sparked.host/irolopezug.properties OCM will throw this error rapidly.

Does this also happen if you have the exact same setup but run the server using Spigot? I suspect Purpur might be doing some wacky optimisation with the packets

Sry, ment to try this 4 days ago but my brain shifted from that to doing something else, so did yesterday.

I might just not test it as I somehow keep forgetting to do this...
