We’ve identified an issue where locked, dyed shulker boxes do not drop the shulker box entity or object when broken. This behavior has been traced to a third-party plugin, and a temporary workaround is available in a recently published support article.

We are actively working with the plugin developer and expect to have this issue resolved in the near future. For updates, please monitor this status page or refer to the support article. We understand this is frustrating and sincerely apologize for the inconvenience.
