This is my first time posting about this, but I am glad to hear it isn't just me.
I have the "Mob_db_re" in my rathena file and in the database and it seems to be in working order.
I see yours reads the create arrow and then loads the mob whereas mine reads the create arrow then tries to load "null" and then moves to the mob. Is it looking for something that it shouldn't be or is this an issue with the loading _mob
_db
I am however super new at all of this and may be misunderstanding you.
