Crash

[null321-jared]

What steps will reproduce the problem?

1. Create a PlayerNPC
2. Do something that makes it try to use the player's connection. In this case I died near them, but there are times where it seems random. Once it happened when I brought them very far from where they originally spawned.
3. NPE happens, crashing server.

What were you expecting to happen? What happened instead?

I expected it to not crash.

What version of the plugin are you using? Type /version <Plugin Name>

2.3.1

What Spigot version are you using? Type /version

1.11

Do you have an error log? Use pastebin.com. If you're not sure, upload your whole server log

Here's the error: http://pastebin.com/JEdBGrzy

Did your client crash? Upload errors in .minecraft/logs/latest.log as well

It did not.

Additional information? (Are you using Bungeecord? Did it work in previous versions? etc.)

I don't know if this is new or not. It actually sends my server into a crash loop for some reason. As I typed this my server crashed 21 times. I tested it with a backup world and it still happens. It does not happen if I unload NPCLib, so only when it IS loaded.
