Editing the spawn plots are easy- they're just coordinates, stemming from the bottom left corner. You don't need any python knowledge to edit that, just add 15 to all of the x coordinates and 5 to all of the y coordinates. I'm not sure where regions are handled, but it's most likely just a grid corresponding to the map- just copy and paste to Excel or other spreadsheet program, add the rows/columns, you're adding, and follow the format that's given. Simpler stuff like this doesn't actually require much modding knowledge at all, just following the patterns given.
This is the reason why I offered help ^^
I think we can asks programming masters like Embryodead or Leoreth if we find difficulties finding where regions/province are handled.
Thanks, BenZL43, I will send you the file this weekend. (Its only the xml that ive changed. I cant send it during the week cause im 16, and my parents dont give me access to the game computer during the school week.
Okay.. Just send me the .py files only that you need editing, don't need to send me the XML etc because I won't understand anyway

Btw, so it's fixed that the map expanded 15 tiles west and 5 tiles north and south? You're not expanding to the east as well? (it's easier than expanding to west)
