Good day,
I'm using FE 1.4.4.1182 my modded server 1.7.10 with Forge 10.13.4.1558.
The server worked well and normally, but a user notice me it was closed, and check the console had crashed, attached to the report and the last log.
I hope you can help identify the problem, just comment that FE does not seem to work with vip slots.
Thank you

I guess this was a fakeplayer issue.

Looks like it is happening here. Though there is only 1 thing that could be null, (player.playerNetServerHandler).

Can you give me more information so I can replicate this error?

@HeberonYT Please provide me more information about what mods you are using with forge essentials, etc.
