OSRS Nex records rewritten: the 643-PB bug cleanup explained
On 2 September 2026, as part of Summer Sweep Up Miscellaneous, Jagex confirmed a Nex personal best cleanup: 643 records set with bug abuse had been reverted. The first batch came from last week's Mad Angel Combat Achievements bug, which inflated NPC damage calculation game-wide and produced Nex kill times as low as 4.2 seconds — initially 83 PBs, expanded to any sub-70-tick time in the bug window, affecting 154 players. The second batch came from revisiting a 2025 Verac's bug that allowed Nex's minions to be killed in an unintended way, adding 489 more PBs. After the corrections, the Nex record should sit at 42 seconds, and Jagex invited reports of other unrealistic bug-based records so the same standard can be applied across all bosses.
Key takeaways
- 643 Nex personal bests removed for bug abuse (2 Sep 2026).
- 154 from the Mad Angel Combat Achievements bug (kills as low as 4.2s).
- 489 from a revisited 2025 Verac's bug on Nex minions.
- Corrections set the record back to pre-bug values; now 42 seconds.
- Jagex will apply the same standard to other bug-based records.
What happened
The Mad Angel Combat Achievements update on 26 August 2026 introduced a bug that affected NPC damage calculation across the game — including at Nex — which let skilled teams produce kills far faster than the boss's mechanics allow. Community reports surfaced kill times as low as 4.2 seconds, impossible without the inflated damage.
Jagex's initial review flagged 83 extremely fast personal bests from that window, then widened it to any PB below 70 ticks (roughly 42 seconds) set during the bug's active period. Combined with a separate revisit of a 2025 Nex bug — where Verac's was used to kill Nex's minions in an unintended way, leaving 489 PBs from that period unaddressed — the total came to 643 record paths corrected.
- Root cause: Mad Angel Combat Achievements damage-calculation bug.
- Impact: Nex kill times as low as 4.2 seconds.
- First batch: 83 PBs, expanded to 154 players (sub-70-tick).
- Second batch: 489 PBs from the 2025 Verac's bug.
- Total corrected: 643 personal bests.
The record after the cleanup
After restoring the affected records to their pre-bug values, Jagex states the Nex record should sit at 42 seconds — a time they consider achievable without relying on any bug. The rewrite was expected to take effect within roughly 24 hours of the announcement.
The dev team also explicitly said remaining personal bests are considered achievable, and invited players to report other areas with similarly unrealistic bug-based records so the correction standard can be applied consistently across the game rather than only at Nex.
Why it matters for your account
Personal bests feed several visible surfaces: the speedrun board at Nex's lobby, the Combat Achievement kill-speed tasks, and community leaderboards that rank world records. A corrected PB can retroactively change which CA tier your account is shown as completing, so players who had a lucky bug-window time may need to re-earn it legitimately.
For most accounts the impact is cosmetic — PBs are bragging rights, not a gating currency. But if you were chasing the Nex speed-rush Combat Achievement, this is the signal that the legitimate target is the 42-second barrier, not the impossible sub-10-second times from the bug period.
- PBs feed Nex lobby speedrun boards and CA speed kills.
- Bug-window times are invalid for CA credit.
- Legitimate target: sub-42 seconds, now achievable without bugs.
- Other bosses may see similar cleanups.
Questions players ask
Why were Nex personal bests removed?+
A bug in the Mad Angel Combat Achievements update inflated NPC damage game-wide, allowing impossible Nex kill times as low as 4.2 seconds. A 2025 Verac's bug was also revisited, bringing the total to 643 PBs corrected.
What is the Nex record after the cleanup?+
Jagex states the Nex record should now sit at 42 seconds, achievable without bug abuse.
How do I know if my Nex PB was removed?+
If you set a PB during last week's bug window or during the 2025 Verac period, your time may have been reverted to your pre-incident best. Check the Advice Grym in Nex's lobby.
Do removed PBs affect my Combat Achievements?+
Kill-speed Combat Achievement tiers rely on achievable times, so a bug-window time is invalid credit — you may need to re-earn the CA with a legitimate kill.
Will other bosses get the same cleanup?+
Yes — Jagex invited reports of similarly unrealistic bug-based records and plans to apply the same standard across the game.
