The “Shop”, “Clans”, “Referral Program” tabs don’t open in the game in 1.13 WOT. It’s a bug and the usual issue after EVERY update of WoT…
If you have this problem after the update, here is the solution:
After the 1.13 update, some players have problems opening windows using the in-game browser. May be unavailable: Shop, Clans, Referral program, Field mail, etc.
As a workaround, do the following:
1. Close the game client completely.
2. Download the file from the link:
• Yandex.Disk: https://disk.yandex.ru/d/0Kbj3wC7r0_qtA
• VK: https://bit.ly/3gV9Lyd
3. Unpack the archive.
4. Place the engine_config.xml file in the /res_mods/1.13.0.0 folder.
* For example: C: /Games/World_of_Tanks_RU/res_mods/1.13.0.0.
5. Restart the game.
