Has anyone experienced this bug before? The bug is that sometimes I can't click on anythings and can't use hp nor mp potions. This is very annoying and affects my game play a lot (die when fighting boss/in war due to not being able to use hp potions), but it only happens once every 5-10mins, I also can't put stuff into my inventory, can't pick up item/switching my gear, using warp nor hp potion and extracting stuff (click on but nothing happens) both in war and dungeons/fields.
Also it seems like I cannot check personal shop whenever this problem happens as well
This only happens on one of my characters, even other characters on the same account don't have this problem. I've also created a different account and this bug did not occur no matter how long I played on it. I've tried to reset the settings to default and reinstalled the game but it did not solve the problem. I've already submitted a ticket a while ago but they said there is nothing wrong with my account and blamed it on latency even though I mentioned that it only happened on 1 character. I had to play with this bug for months and it got worse after every maintenance (i.e the bug happens more frequently). I included some videos bellow showing the problem.
