Is there anything special that needs done to set up a server or does anyone have any tips what this issue is? I've done what I typically do when setting up a modpack server (download via launcher, run once to create config files, copy everything to my server machine & copy to a minecraft profile so we can launch from the vanilla launcher, remove any client-only mods from the server, add Admin Commands Toolbox to the server, launch everything up). While I'm able to connect, the server is acting like there are differences in config files between the client and server - I noticed when trying to make wood from the ... dead wood? (I'm at work now so I can't remember the item names), where the crafting table would show a valid recipe but when I tried to pick up the completed item it would vanish. I even tried to copy config files from the server instance back over to the client & relaunched but the same issues kept happening.
