This happens whenever a Player logs in.
I am using Holographic Displays to display damage indicators, and using ProtocolLib to disable the Damage Indicator particle via packets.

Whenever I log in, the server crashes.

I'm on 4.5.0-Snapshot, should be latest.

Should be fixed in the new dev builds, which build are you using?

I should be on the latest from May 7th or whatever, let me check again.

I deleted and re-created a new world, issue is still happening.
Holographic Displays 2.3.3 and 4.5.0-Snapshot ProtocolLib

References: filoghost/HolographicDisplays#135

Please refer to the above for some more info. At the moment we think the issue may be in ProtocolLib and due to some structural changes in the 1.14 code and/or the spigot changes on top (it's tricky because there's another error that pops up referencing methods removed by spigot and are not related to this particular error)
