Bought your Kobolds and Cultists Map and like it.
But I had problems while importing. I had to manually edit the File and change the format_version="4" to format_version="3" because RW failed with the error "format_version out of range" (I have the latest Version of RW).
It would be great if you provide some information in the zip which game structure is used for the module.
Some more :-) Based on your name I guess you are german or german speaking. If I am right and you translate your module only for drivethru, it would be great if you considerate to publish a german version too.
