Ordinals founder Casey said on the X platform that if users use ord to send runes, please upgrade to ord 0.21.2. This version fixes a somewhat serious bug that "ord wallet send" does not create a change output in some cases, which can lead to missing runes. This bug has been fixed in this PR. When using "ord wallet send", the wallet must select an input UTXO that contains enough runes to overwrite the amount sent. The release also includes: ord wallet sign can be used to sign messages through an address in the wallet; if the casting is currently open, the casting progress is only displayed on the /rune; the casting progress is also displayed incorrectly, which has now been fixed.
