Log files showed nothing on the error just that players were disconnected.

on placing a clay soldier it just instantly disconnects all players on, cant rejoin the server until its restarted and the mod is taken out.
No disconnect reason logged in the server logs and our player data is saved threw nucleus which just stores the uuid, name, logoff cords and effects on player at the time.

I cannot reproduce it. Can you give me the log files from the server and a player that was kicked from it (even if you think there's nothing in there)?

That's a Sponge server. I suspect that they do something differently than a vanilla Forge server causing issues, since I cannot reproduce it on my own and the log you gave me doesn't indicate on any wrongdoing on my part.

I suggest bringing that issue to the Sponge devs, they probably have more of a clue what's wrong than I do: https://github.com/SpongePowered/SpongeForge/issues

ok i will do, thank you.
