duplication bug

[PineconeCat]

found this strange bug with flax twine, I cant remember correctly but I was crafting some linen and some of my twine disappeared. Later, I got enough twine to make more linen and when I crafted the linen some new twine appeared in my crafting? I thought the old twine had returned so I crafted more and it kept happening. I haven't been able to recreate it but now I just have these 6 pieces of twine that always duplicate when crafting

I was crafting again and now its down to three infinite twines, and all the linen I craft in my inventory disappeared but one? Now all this "fake" linen I craft cant be combined with this one linen that didnt disappear the first time.

Try exiting the game and loading again, maybe the phantom linen and twine will sort themselves out?

Turns out anything made from the fake linen disappears after a while  all thats left is the duplicating linen

Welcome to the game and forums.

Yeah, crafting is rather wonky right now. Don't know when it broke, if it's a 1.22 special or I just didn't notice it much on 1.21? But the client desyncs from the server quite often, leading to crafting being broken potentially until you relog/restart. Best case scenario you get ghost crafting like you described, where the client thinks something is crafted just for the server to disagree - which results in the "crafted" items vanishing (cause they never truly existed) when interacted with and the ingredients returning to the crafting grid when prompted, worst case you can't craft anything in the first place because the recipe glitches out and no output items is displayed. The latter is, to my knowledge, only fixable by rejoining the world.

There is a mod that tries to alleviate the pain, though I cannot personally say how well it works as it, so far, did not seem to do anything on my already heavily modded game.
