Before Continuing:

 Check you are using the latest version of the mods and its dependencies

 Always include a latest.log if you are crashing

 Remove known hacky mods such as: Optifine, Fabric API/Connector on forge, and every kind of hybrid server like Mohist and Velocity. None of these are supported. Also try without other lesser usual suspects like Sodium and Lithium.

 If you are unsure which mod is the culprit.
Disable all of your mods and enable them 1-2 mods each time to isolate the culprit

 Confirm that there is no existing issue with a similar description submitted in the list of issues.

Describe Issue

Like title says, bells break whenever the rope or chain they are hanging from is pulled. (looks like other "attachable" blocks like lanterns still work) heres a video about it: https://github.com/user-attachments/assets/6791f1cc-e1d8-4b8f-bc9f-2e20b8dbb173
