Gm.... why mystic door like this?

Gm, why i always use mystic door and after i enter the door to town, then i can't see the door anywhere, like dissapier already. =.= but the skill still got on top of the screen. this happens everytime i use mystic door, makes me hav to walk back to the training place. =.= pls help, thx

psps , i found out tat its not that the door dissapier , but its because if u enter the door, it brings u to other places in the town but not to the door in the town , and the same goes for going back to the training ground. Gm can u fix it? make it lead to the door and don go other places. thx
