Not played on Arkadia (or PE) for a while so I'm feeling a little lost atm. My main 'area of ignorance' is about this new underground instance. I've managed to get the Vault keys 1 and 2 but whenever I use them I get a 'gate not found, coordinates don't exist' type message. My presumption is that these aren't the keys to get underground as I thought they were, but maybe to get into certain places when underground? As a random test, I bought an Arkadian Key 6, this gave me some co-ordinates, I went there and found....... a bush, but no apparent entrance (which is strange cos I thought the two went together). Obviously I've missed something or I need to RTFM, so to speak! So, what missions do I need to do, or what do I need to buy, in order to get a usable keys/items that will get me underground, or are there a set of instructions anywhere I can read to tell me what to do? Thanks for helping this old noob.
