Reason for incompatibility found: Game uses signature files

[HazardMOD]

Did you figure out how to get it working with those signature files? I'm in the exact same boat, any help or links I'd be very grateful! Or if anyone else has any more info

[Buckminsterfullerene02]

Try copying the .sig files in the Paks folder and rename them as the same name as your mod pak file

Having the same issue on a 5.4.4 game that does not use signatures.

[HazardMOD]

Mine says the same thing on a seperate UE5.3 game with no signature files, only pak

Actor for mod 'MMode' is not valid
I also encountered this 5.4.4 version
