Strange error with magic-spoiler.mse-export-template

Hi,

I hope I'm in the right place, my apologies otherwise.

I'm running MSE 2.1.2, and using the "M15 Extra" Template so I can use extra colors like pink and purple. I use an older export template called "Spoiler" to export my creations to a simple HTML list with card images (for showing my ridiculous creations to my playgroup).

I had to re-install everything recently, and since the re-install, I get an error when I try to export to HTML using that combination of templates.

I get "Variable not set: card  in function ancestral_mana in function to_html".  I've come up empty looking through the files for references to this function or for any hints at a fix online.

Any thoughts, or export alternatives?

Note: I use M15 Extra instead of M15 Mainframe, because in Mainframe, I can't use the pink and purple mana symbols in casting costs for some reason, and I haven't figured out an answer to that either.

Sorry if these are "noob" questions.

Thanks in advance!
