I dont know is it a bug or not, but i got this event(?) for first time, and he didnt want to give up even if i turn off computer. I restart the game, delete all messages and in a few hours he did it again, and he countinue to spam and drop my fps from 160 to 8-10, so on this moment i restart game again and only then he stopped. i dont want to delete 500+ messages and want to ask, is it possible to delete all this in one-tap? thank you.
