@fanthom, @brokenman: I will try to eliminate it

Regards!
EDIT: Found the cause! All modules made by me (at least) using the saves-time tool and not post-cleaned to eliminate the trash, are contaminated with it! To eliminate it completely is a work of ants. I will post the list of modules that I clean. . . .
Cheers!
