Codes follow updates, not only milestones
The pair live on 2026-10-29 is named after two updates, HALLOWEEN and PET, while the previous pair carried concurrent-player counts. A retired code stops working for every account at once, so a failure usually means the update it was named for has passed rather than a typo.
Balance changes move the guides
Upgrades, ore values and gear outcomes are the parts an update can shift. The in-game upgrade screen and the Forge preview show the current numbers; the guides here say which screen answers which question.
Creator sources beat reports
The official Roblox description is the one surface Good Bro Studio controls, so it is the first place a new code or version name appears. Community trackers are useful for rewards the creator does not spell out, and the pages here label them as reported.
