the thing is with ingame one i'm unsure if able to create warps etc(ik on one you can use images/tiles etc) but allowing warp coordinates etc would end up abused even the images allowed could aswell if not just set image of say tree/s etc. For server like classic with how many people would be lot of uploads aswell unless it had like 30k upload or something but that'd possible be for 1level that ends up matching upto inside levels of houses etc already ingame. idk I can understand why this hasn't been released on any server yet as there is lots to be overcome before it'd ever get to point of release thats kinda a shame.
