Your exported db folder comes empty.Do you mean the the exported_db folder was not empty in the last version of the server I shared. I need to check that, but that surprises me.
Indeed the doesn't need you to add the stadium from your db to the map file.
But the the app doesn't read the IDs it get them from the db files from the exported_db folder. Stadiums.txt file.
What I meant was, It wasn't necessary put the Stoke and Bournemouth in the map_stadium.txt, because they have yours onws stadium in the db.
What I don't uderstand is: Stoke stadium is id331, Bounemouth is id348 and the tool try to load the id267. There's no stadium 267, even in my db or stad_source_files.zip.
