Description: Server: potato, haven't tried on carrot Expected behavior: assign or clear item being filtered by the filter hopper, set whitelisting or blacklisting for the hopper Steps to reproduce: try normal filter hopper item/listing actions, no changes occur How long ago was the bug introduced? Unsure. I just started using filter hoppers. I have three filter hoppers on potato that won't let me change the item they're filtering. One is set to none, and two are set to wheat. I also can't change if they're whitelisting or blacklisting. Doing the normal clicky stuff for setting the item or changing the white/blacklisting has no effect on any of them. I'm not sure if I'm being dense (not ruling it out) or if I'm having a technical problem. Any help is appreciated.
