Cached pointers are generally dropped, not moved: this led to an assertion firing in the data update path when there were no new replicas being written. This path adds a data_options field for pointers to be dropped, and tweaks move_extent() to check if we're only dropping pointers, not writing new ones, before kicking off a data update operation.
