## Sheldon AI — V21

- **Admin actions now actually run.** Sheldon can carry out admin commands on your
  behalf — set the time, give items, broadcast to the server, or run any console
  command. (Admin-only; previously these were acknowledged but didn't execute.)
- **F8 chat opens at the newest message** instead of scrolled up to the top.
- **Fixed the "Sheldon AI" buff icon** so it shows at the right size alongside your
  other buffs.
- **Behind the scenes:** more reliable tracking of dinos near you on busy maps,
  steadier replies when several players chat at once, and internal cleanup.
