Problems delivering quests

[Chlebeg 0]

Hello, I started playing the game after about 3 month long break. I did my updates etc. I noticed that whenever I have a quest for simply killing some mobs I cannot deliver it. The game says something like "kill x 12/12" and no matter how many of them I would kill, the quest won't change its status for me to be able to deliver it. It just keeps counting killed mobs. This does not occur with quests when I have to kill some mobs and loot them for some items, these work fine. Any ideas? I did restart my computer, I did check my files.
