At this file location, my "users" folder is empty after each modpack installation: C:\Users\"USERNAME"\AppData\Roaming\Wargaming.net\WorldOfTanks\xvm\users\. As a result, things like my carousel reserve tanks (reserve.dat) are gone/deleted and I have to resave them all individually inside the game client. I noticed my reserve tanks were not saved with each new modpack install starting with Aslain v1.14.1.3_01, or perhaps even earlier with v1.14.1.2_xx. I finally did some researching and isolated the problem with the empty "users" folder. As a work around, I am copying my "users" folder to a backup location and then with each new modpack install, I'm pasting my "users" folder where they should be. It's saving me from having to reselect my reserve tanks for each of my WoT accounts, which was a real pain.
