Basically, hoppers were disabled or are bugged. My semi-auto brewer broke and they are a fairly essential item in automation. Please fix/re-enable them!
they will be fixed when the dupe issue is patched by microsoft. Unless you want to go code a plugin that is compatible with all the other plugins you can kiss your hoppers goodbye.
Quick note! Be aware there is already a thread on this! For further updates and more info on the hopper problem, refer to http://www.mineverse.com/threads/hoppers.50734/#post-516922
