1.8 Forge Server Disconnects AFTER Loggin In

[LawfulFelafel]

Hello,

I am running a forge server for 1.8 (latest stable release) with one mod: Build Faster V3. When my friend tries to connect, he is able to log in for 30 seconds to 1 minute, then is disconnected. There is no error message, it just says Connection Lost: Disconnected. When he logs back in, he sees that his work is undone, and that the server has not saved his changes. I have tried canyouseeme.com and it reports that it can connect to the server. Any ideas?

 

This is the log leading up to one of the disconnects:
