[Bug]: Connection to server reset when mounted on dragon

[Hoadaus]

What happened?

In a server on a custom modpack. No issues with anything else in the pack. Pack has been running for several days. Found and hatched a dragon egg. Dragon was grown to stage 3, 4 and 5. At all stages, riding the dragon causes extreme latency before finally disconnecting from the server. This is repeatable every time and only occurs when trying to ride a dragon. This issue does not occur in a single player environment.
Attached are the exact message given client side, and the readout of the server leading up to the disconnect.
