Exactly the same here! Got the "unsuitable version" notice, which I ignored, just installed as usual using Aslains installer. Started WOT up and got stuck at the loading screen whilst synchronizing "loadout and equipment". This process, when switching vehicles, took ages in the last 1.1 version (with mods installed) too!. I don't use garage switchers I believe, I like the field camp best. Reminds me of my army days. I do have carrousel mods and most importantly a mod that auto switches consumables and equipment, I suspect the reason for the apparent "freeze up" can be found in that area. Like always, the kinks will be gradually ironed out and all will return to "normalcy" after a few mod upgrades.
One does ponder why every time there is a patch, the mods get haywire too??? That should be avoidable......no?
