Going to bump my own (really old) topic here, as I just ran into this issue on another site I run. On this site we have some TL4 users, which means they can pin topics. One of them pinned a topic globally, which should have been just a normal pin, so they unpinned it and re-pinned it. Afterward, they tried to delete the original “pinned globally” small post, but found that it triggered the “to be deleted in 24 hours” text. There’s no option to flag a small post, so this seems like a bug (will make a separate #ux topic, not quite sure it’s #bug level). In any case, allowing for an undelete/cancel delete would solve this, as I (the admin) could then go and delete it without the delay.
