Hello.
This is showing as something not existing from Forestry, looks like your server has it, and your client doesn't, or your client has it, but the server doesn't.
Work out which one it is could be different versions of forestry.
Can you download a server fresh, and a client fresh, let me know if you get the same response. If so, can you try a new world.Luke, we're using the FTB server and FTB Launcher with nothing disabled... if this is the case then it would be something the downloader from FTB launcher has provided us?
