Clients crash on Server 1.7.10

Hiya and thank you for your time. 

 

I am hosting servers. The current sever is a custom version of Hexxit with updated mods. I and the friends removed two mods and added three. I accepted the warning about items removed and they could logon for about a minute or two then there game crashes with a error found here.

I was wondering what if any advice I could do to fix the issues of the server.

The server run forge 1.7.10-10.13.4.1492 The client is Techinc launcher mod-pack that I maintain. The server logs are listed below and I separated the logs with ## fml-server-x.rb.
