Yes. I had encountered this issue too. I've tried many configs, different modpacks, nothing has changed. But one thing worked for me and all seems to be working as it should now. I've manually deleted content from C:/users/x/AppData/Roaming/wargaming.net/WorldOfTanks folder (where x is your account name). Oh, I've deleted the folders, leaving the preferences.xml. After deleting this folders just run wot and let game recreate them with files inside. I've logged in many times and changed tanks in hangar again and again and the dynamic data on the right works all the time.
