You can easy replicate this error, it will work 100% of the time
If you login to the orginal client before you open the mirror client you will always have this error, no matter what
It's bin like this from the start mirror has b en released, login whenever both client are loaded to properly start/load all the entities in game. If you login before the mirror client get hooked, it won't load the current objects in the loaded region, thus it can't interact with object and NPCs
That's the issue you were getting, can't open bank, can't interact with the ditch, can't interact with the mage.
but I'm glad it's working fine now! ^^
