Disappeared mod!

[R'as al Ghul]

I now find that, when I run MTW, my mod no longer appears on the era selection menu!

This usually points at a problem in your startpos file. The one that doesn't appear.

So the situation is that my 'EYG' prod files call for Custom0-Custom6 on numerous units but the default Crusader_BUILD\UNIT_PROD files are still in their original state.

Do I have to alter the Crusader and Vikings prod files to also reference the custom0-6 terxtures or something?

No. They have nothing to do with each other, meaning they don't influence each other. Changes in your own prod files or startpos have no effect on the vanilla game. Also, what would you reference?

I'm guessing that the game has to read various important files at startup because the strings which display on the era selection menu are in there. Could it be that it doesn't like the 'hybrid' state the game is currently in?

I can imagine that if your errorfree startpos points at erroneous prod files, you'd miss the era in the menu.
If your own startpos has no errors and points at unchanged vanilla prod files it should work.
That it does not indicates that your startpos file is wrong, after all.

Hope that helps.
