Not working for any oven types since the July update in my environment. I think we will need a version update with a fix.

Failed to call hook 'OnTick' on plugin 'FurnaceSplitter v2.2.4' (InvalidCastException: Null object cannot be converted to a value type.)​

I still get the same error, but haven't tried restarting the server.

Edit: The same error with 2.2.6
