The Dragon Slayer II quest trailer shown at RuneFest is no longer available from Jagex's official channel. Jagex said on Reddit that it removed the video and opened an urgent investigation. The clearest problem in the footage was a character's hand with six fingers.

Jagex did not say the entire trailer was generated. Its statement is narrower: an external partner produced the material after explicitly confirming it would not use GenAI. The studio also accepted that its own checks failed before the trailer reached the audience.

After RuneFest, Jagex plans to overhaul its review process.

It also intends to commission community creators to produce new material that tells the Dragon Slayer II story. The statement announces no changes to the RuneScape quest itself or to game assets. This is a marketing and supplier-control problem.

The timing made the miss harder to dismiss. Days earlier, Jagex had dealt with GenAI concerns around a 100 Thieves apparel collaboration for Old School RuneScape. Both incidents involved outside partners the studio said it trusted. Written promises were not enough, and final approval did not catch the result before publication.

The part worth watching is the process. Jagex now has to inspect finished work instead of relying on contract language and a partner's reputation. The RuneScape catalog page has the game's details and our other coverage.
