Mods not working

A mod that worked on 4 Nov 2026 can sit dead on 5 Nov because Dawn of the Delta and Update 3.0 shipped together. The FAQ’s position is that Ubisoft does not guarantee compatibility and does not fix mods for authors.

• Read the mismatch dialog and the pause-menu mod icon. If the game does not list your file, it is not loaded.
• Comment one line in active-profile.txt with #, then load a new save or a save from before the break.
• Do not disable the whole folder at once. You will not know which file mattered.
• Check that friends in multiplayer have the same versions, including sub-mods.
• Missing requirements fail the same way as a bad port.

I am not publishing a blacklist. No 3.0 compatibility sheet from Ubisoft names individual mods, and a guess would blame working files. If the author has not posted a 3.0 build on mod.io or Nexus, assume the old file is stale.
