One of the biggest overhaul mods for Total War: Warhammer III has just been sabotaged on purpose – by the person who made it. Veteran modder Venris announced that he deliberately corrupted SFO: Grimhammer III so it no longer works with unauthorized reuploads, after people started using AI to publish sub mods of his work without asking.
What actually happened
Venris has been building the Simply Fun Overhaul (SFO) family of mods for Total War: Warhammer for years, with development funded through a Patreon. The latest version, SFO: Grimhammer III, reworks the base game to sit closer to the Warhammer lore and setting – it touches campaign and battle mechanics, the economy and customization alike.
Recently, other users began releasing AI-made sub mods of SFO: Grimhammer III that patched it to run with newer builds of the Creative Assembly game. None of them asked for permission. Venris responded by breaking his own files so the mod stops functioning alongside those uploads, and warned he may pull it from public view entirely.
“Due to the growing number of unauthorized reuploads of SFO: Grimhammer III, and more importantly, the use of AI in the process, I have deliberately corrupted the mod to prevent it from functioning with such unauthorized uploads,” Venris wrote in his published statement. He added that if the situation keeps escalating, he will make SFO: Grimhammer III private.
His reasoning is personal: the mod is the result of nearly ten years of work for the community and the fantasy world around it, so he does not permit anyone to take it without permission – “especially not for AI-related purposes.” He signed off with “Support modders, not AI.”
What this means for you as a player
If you run SFO: Grimhammer III through the official Steam Workshop page, the practical takeaway is simple: stay away from third-party reuploads and AI-patched sub mods. Those are exactly the combinations the author targeted, and loading them can leave you with a broken setup rather than a working campaign.
- Use only the original, author-maintained version of the mod.
- Unauthorized reuploads are now intentionally incompatible.
- There is a real possibility the mod goes private if the reuploads continue.

The bigger AI modding fight
The clash does not exist in a vacuum. Recent weeks brought a wave of AI-generated “mods”: viral clips of game-merging experiments, AI versions of titles running on platforms they were never officially released on, plus AI-added features, raised player counts and mashups fusing two different games together.
That wave has triggered questions about legality and about whether traditional modding stays viable at all. Parts of the modding scene have reacted with shock and disappointment at AI clones and mashups. Publishers face a sharper version of the same question – why buy a new Fallout game if an AI can produce one in minutes? This week the creator behind a viral AI-generated Fallout: New York project took it offline after receiving a cease and desist from Bethesda, a move fans openly celebrated.
Reactions to Venris’ decision split along the same lines. One commenter mocked the statement as bureaucratic gatekeeping, while most sided with the modder – one reply noted that anyone who thinks he is in the wrong has never had a major chunk of their life’s work stolen.
