If you are using Menyoo, go to teleport, scroll down to offices and scroll down to Maze Bank and choose Warm.

If you are using simple trainer go to teleports, other teleports, office and warehouses(Enable Mp MapsOption) Then go to Maze bank and select Old Spice warm

It might say loading online when using menyoo to teleport to the office but it is not just wait for it to stop loading.
