Hi.
Check this issue with some explanations: entdark/JKChat#1

If you want to make it work then you need to add implementations for entityStateFieldsMBII and playerStateFieldsMBII with modified net fields:

JKClient/JKClient/Message.cs

Line 658 in 19804d1

private static readonly NetFieldsArray entityStateFieldsMBII = entityStateFields;

JKClient/JKClient/Message.cs

Line 1084 in 19804d1

private static readonly NetFieldsArray playerStateFieldsMBII = playerStateFields;

The modified fields could be found in MBII assets.

I added the needed overrides to my fork. Seems to connect now. Copy them if you like.
