Could not reproduce, maybe your file was not downloaded correctly, re-run the installer with clean up dlc, to redownload the files again.
Do you have a hitzones menu in garage? Like on this example picture:
Brak dostępu do konfigu: IOError: [Errno 13] Permission denied: u'C:/Users/Acer/AppData/Roaming/Wargaming.net/WorldOfTanks\\modsettings.dat'
To jest powodem ze te mody nie dzialają. Wykasuj recznie ten plik i przeinstaluj paczke. (w exploratorze windows wpisz %appdata% itd.)
ASIA has not received 9.17.1 update? If you still have old modpack for 9.17.0.3 use it, and it will fix it for you, or manualy recreate missing paths (from error window).
Don't use new mods/modpack for now.
Mod is located here: mods\0.9.17.1\mod_vehicle_exp.wotmod and here mods\configs\wotfan_mods\mod_vehicle_exp\mod_vehicle_exp.json and the rest is in AppData\Roaming\Wargaming.net\WorldOfTanks\modsettings.dat (garage menu)
Usun ten mod i zobacz wtedy, trzeba by moda przetestowac na jakiejs treningowce, byc moze nie dziala jak powinien, albo dziala a ten kto klika, przesadza
