I updated my pack to version 3.3.298 and when players tried to craft in their inventory grid, it wouldn’t allow it. It would allow placing items and show a completed product but wouldn’t let them take it.

Are there any errors in the console log when this happens?

I don't see any but this is my console log after trying to make a crafting table https://pastebin.com/tCsT5XQ8

I still can't seem to recreate this in-dev and that log doesn't appear to have anything relevant to the reason as to why it wouldn't work. Tried both in single player and on server too. I wonder if it has something to with another mod interaction interfering with the detection.

Well yes it would likely have something to do with the newer hooks that listen to inventory changes. If it's related to #605 then something was changed with the assumption that all inventory listeners are players.

I am sure it is. Would have to go mod by mod at this point. It is a problem when I update your mod only. Crafting works with all the other mods hehe
