Unfortunately when a player is near a Thaumcraft golem with AM 2.5 version 1.6.1 or 1.6.2 on a server it will boot the player off saying there is a no such method error and then a ticking player exception occurs. Tested with a fresh world on the server as well. This was the exception I was able to grab from server logs :

Works completely fine in single player. I was able to revert back to version 1.5.0 hotfix and confirm the issue does not exist in that version.
Unfortunately when a player is near a Thaumcraft golem with AM 2.5 version 1.6.1 or 1.6.2 on a server it will boot the player off saying there is a no such method error and then a ticking player exception occurs. Tested with a fresh world on the server as well. This was the exception I was able to grab from server logs :
