played 250h nightmare lv 212

yo devs, do you ever test when you update the game?
To be honest, I understand that yo guys will fix the weird optimizations in the next update
but are other bugs (balance, crash, stuck, ping explosion, skill bug, clearing zombies mission issue)is this a major issue that can't be fixed even with a hotfix? is it difficult?????????

i wonder how many characters have already flown away thanks to you guys haha
