Is there an English version of the Munchkin module somewhere?
Yes, yes there is.
If it is in English, where is it?

If you look at the Munchkin module: vassalengine.org/wiki/Module:Munchkin
We are not allowed to post any links to those file…
But a simpel Google Search: google.nl/search?q=vassal+munchkin+module
