Attachment Crash Suppressor
by DimasKama
Attachment Crash Suppressor stops a client from disconnecting when the server sends an attachment change for a target the client does not recognize.
What it does
When a received attachment change names a target the client cannot find, the client normally drops the connection with an error. This mod intercepts that case, so the disconnect with its message does not happen and play continues. It is built on the fabric-data-attachment-api and requires Fabric API.
Only the client needs it, so servers run without it and players install it alone. Files are published for Fabric, covering game versions 1.21.10 – 26.3, and the code is released under the CC0 1.0 Universal license, which places it in the public domain.
Key features
Blocks unknown attachment targets
Attachment changes aimed at a target the client does not know are ignored instead of ending the connection.
Shows a disconnect message only when needed
Where the disconnect would have happened, the mod keeps the session open rather than displaying the error screen.
Built on the attachment API
It hooks into fabric-data-attachment-api, so it works with the attachment system Fabric provides.
