Demounting mods from worldbuilder

I installed Blitzkrieg mod with the HD textures the other day. But upon entering the worldbuilder the hd textures are still in place and don't represent the look when played in vanilla. Is there a way in which to demount mods from the world builder to address this issue and also that of placing incompatible objects so that the map can easily be played in any version of the game without "missing lua" boxes all over the place?

Yes, Worldbuilder always loads the first mod it can find in alphabetic order. So it finds "Blitzkrieg.module" before "RelicCoH.module". Just rename Blitzkrieg.module to zBlitzkrieg or move it out of the folder. Rememeber to make that with every mod you use if there is one with A-R in the beginning.

Thank you so much, I have been trying to figure this out forever.
