Well, kiss animations is least of my problems with patch 4
After update Act 3 is almost unplayable. When party enters new area (for example wyrm's rock), whole environment becomes unresponsive. All npcs and party members are stuck in place, they won't follow. Cutscenes won't trigger. After 2-3 minutes bug goes away. (No mods).
I made support ticket, I really hope there will be a hotfix soon.
