Walked into an area that had a frog from an older version of the mod in it (from the builds in actions), and immediately got booted from the server with this error. I cannot relog into that area without getting booted with the same error. Is happening as of build#1635

In addition, a simple question, what's the safest way of removing the mod from a server? because simply removing the mod's .jar certainly wasn't it.
