When FurnaceSplitter is disabled it works fine.

Did you remember to set the user permissions?

I've been testing this with other players and it appears to be only that one player it happens to. Permissions were all set ok. It's still not working for that one player for some reason.

Same thing is happening to me, out of 20 players, only 2 players aren't able to use furnaces at all when the plugin is enabled.

Only fixes for them if I revoke permission to furnacesplitter or disable the plugin.
Tried clearing data file & cfg, didn't fix it.
