Attack Bug(?) when attacking mobs

I need help! Like the title said, even if i use grimoire bot or not, sometime when farming monster i cant attack/skill them. Its like the game pausing, but i can still leave the map, chat. The problem is only attacking. My connection is good too. Why is that happening? Its annoying when you leave pc for botting then this happened. Sorry for bad english, i hope you understand.

this is a problem with the servers. it has nothing to do with u, I recommend not playing on artix or galanoth if that bug happens

also your english is fine, better than @Poonce 's for sure

You mean your class skills are not cooldown? yeah that happens with me too.. I used to fix it in a way relog, join /newbie, kill random monsters (fix) and start the bot again, it is caused by a ping drop~
